Giant swallowtail butterfly with damaged wing

The Backyard Bug Blog

National Geographic has declared 2018 the year of the bird. On this page of the WFSU Ecology Blog, however, it’s the year of the bug.

Here’s the idea:  I’m taking photos of every bug I see in my yard for the entirety of the year.  I’ll identify it if I know what it is, and I may look up others if I have time.  My goal is to see how many different insects, spiders, worms, etc. I’ll have seen by the end of the year.

Subscribe to the WFSU Ecology Blog to receive more videos and articles about our local, natural areas.

We’ll see how bugs interact with different plants, the soil, and each other.  Who’s eating whom?  What are they doing in different seasons?  Let’s take a look:

Raising butterflies, if you don’t collect them all and put them in a protected enclosure, is filled with the best and worst of everything that happens in nature.  Today was filled with a little bit of both.  First, the good. Our giant swallowtails keep growing.  Here, you can start to see one start to develop the big head that they get, and you can see its different colors blend, allowing them to better camouflage on the tree bark (or look more like poop).

Giant swallowtail caterpillar.

There are a good five or six giant swallowtail caterpillars on the Meyer lemon tree, two larger ones and a few smaller.  I don’t expect six giant swallowtail chrysalides, however.

Things happen, as we see with the black swallowtails on our fennel:

Black swallowtail, dead and being scavenged.

Bug #66, scavenging a dead black swallowtail caterpillar.

Yesterday, I had three black swallowtail caterpillars.  Now, one is missing, and the one above has been obviously predated.  I didn’t see that smaller insect on it earlier in the day, when I first noticed what had happened.  So I don’t think it’s the culprit, but rather a scavenger.

In another part of the yard, I see another insect feeding on a dead millipede:

It wasn’t the prettiest day for insects in the yard, but it’s not always butterflies, ladybugs, and bees.

I had been wondering where the butterflies were this year.  I know it was warmer last winter, and maybe we had more butterflies year round.  But, common, it’s June already!  Well, today finally felt like spring in the yard.

For starters, today marked the appearance of what might be my favorite caterpillar, that of the giant swallowtail (Papilio cresphontes):

Bug #63: Giant swallowtail caterpillar on Meyer lemon tree.

Bug #64: Giant swallowtail caterpillar on Meyer lemon tree.

This will become one big, kind of grody looking caterpillar, one that will camouflage well on the bark of its host plant, our Meyer lemon tree.  You’ll notice that right now, it looks similar to a black swallowtail.  Once it starts moving through its instars, though, it’ll look much different.

Here’s a closer look:

Giant swallowtail caterpillar on Meyer lemon tree.

I found three caterpillars, and one egg:

I went to Native Nurseries after dropping Max off at camp.  I asked if they’d seen many monarchs, and while they had seen some, the peak season is still ahead of us.  We had a much milder winter last year, which had us swamped with monarchs in March.  So I’ll be patient.  I’ve been checking the milkweed leaves, but the only thing eating them so far are slugs.

Anyhow, when I got back home, I saw this:

Black swallowtail, recently hatched from its chrysalis.

Black swallowtail, recently hatched from its chrysalis.

Also exciting- my captive black swallowtail hatched.  I thought I had been paying attention to its chrysalis to see if it had darkened, but maybe I didn’t when I got home yesterday?  Oh well.  I have three small caterpillars in the yard, and may move them into the enclosure to get more chances at getting that footage of them emerging as butterflies.

As we always do in our house, we gathered around to release it in the backyard when I got home from work.  It never gets old for the kids, or for me.  Max opened the zipper and I got a couple of good shots of this butterfly as it lingered:

Black swallowtail with busted chrysalis.

Here it is with its chrysalis.

Looking at the outside of its wings, you can tell the butterfly’s sex.  That top row of yellow dots has smaller dots than a male’s, so this is a female:

Female black swallowtail butterfly.

It was taking a little while to leave the enclosure, as if maybe frightened by the four large mammals standing around it, staring at it.  Max got it to walk onto his finger, from which it flew up and quickly away from us.

It had felt like a slow year for butterflies so far, but I spotted yet another new species for 2018 while out in the yard.

This morning, my captive black swallowtail got into position to make its chrysalis.  Right on the zipper.  Before getting big, it had eaten much of the fennel plant in the enclosure.  I had a second, smaller caterpillar in there.  Unfortunately, I can’t put in a new plant without opening the zipper.  So I took the second caterpillar out (there’s a smaller zipper on the side) and put it on the outside fennel.

Black swallowtail in its “J” position, ready to spin its chrysalis.

Black swallowtails are kind of unpredictable.  Last year, most of ours spun their chrysalides at night.  Since this one made a J in the morning, I could have expected that it would be done by the afternoon.  It would have been good to get daylight footage of it making a chrysalis, but it wasn’t possible for me to spend the whole day outside with it.  Monarchs are predictable in comparison, usually spinning, and emerging from, their chrysalides between 6-10 am.

I feel like I’ve been seeing dragonflies everywhere else, but finally one landed near my camera here in the backyard.  Generally, I’ve found that these guys stay put when you get close.

Bug #60: dragonlfy.

And here’s an interesting thing happening on a weed I let grow tall.  Every leaf is curled inward, and covered with a variety of bugs:

Bug #61: Some kind of aphid?

I think they’re aphids.  Aphids attract ants:

Bug #62: Ants

Are these winged insects a mature version of Bug #58, or there to eat them, or somehow living in a symbiotic relationship with them?

I’ve already seen ladybugs in the garden this year, and this specific type.  But it’s worth noting its presence, as they like to munch on aphids as well.

Ladybug.

And finally, not a bug, but the molted carapace of a bug.  One of my favorite things about paying this kind of attention to my backyard bugs is seeing these signs of their life cycles: A molted carapace, a cocoon, and the different eggs and larvae.

The first black swallowtail I spotted grew big and left.  They travel to make their chrysalides, and I’ve never spotted one in the yard.  Last year, I shot a bunch of footage of these caterpillars, and I got everything but a swallowtail emerging from a chrysalis.  And I want to finish that video.  So now, this guy, which is from one of the eggs I posted a few days ago, is in the enclosure.

The big news in our garden on this soggy Memorial Day centers on our tomato plants. I pulled these two green tomatoes off of a plant after noticing that they’d been a little eaten.  Here’s what I saw:

Lily caterpillars on a green tomato.

Bug #57: Lily caterpillars, a tomato plant pest.

I went back out and saw that several leaves had a serious problem with these caterpillars.  Searching “caterpillars eating tomato leaves,” I saw a photo of these.  These are lily caterpillars (Spodoptera picta):

Lily caterpillars consume a tomato leaf.

Ouch.  I had some work to do, plucking these guys off.

Checking the milkweed (still no monarchs), I saw this thing.  Is it a monarch predator?

I also kind of liked this shiny beetle hanging out on this coneflower bud:

It’s actually a combination of those and the bugs I saw on May 22.  Does the wingless bug turn into the winged bug?  Or do the two species just socialize?  Hmmm…

Time to check on the black swallowtail caterpillars.  First, I caught the larger one moments after molting.  Caterpillars do this as they grow, shedding their skin and changing their form slightly (they then eat the skin, usually).  The next change for this one is now the big one: making a chrysalis:

Black swallowtail moments after molting into its final instar.

Also, it appears one of the eggs finally hatched:

Seeing the black swallowtail caterpillars makes me want to check the milkweed.  No monarchs yet, but here’s a neat bug:

It looks like the same species of sweat bee I saw on March 23, so it’s not a new species for 2018.  But I do like the way it looks on this swamp milkweed.

Looking over the milkweed, I also saw these crazy little guys scurrying around the lip of a pot:

And finally, a fly on the hydrangea:

So yesterday, I spotted two eastern black swallowtail eggs on our fennel, and somehow missed this guy:

This is a first instar black swallowtail caterpillar.  One thing I like about this caterpillar is that, compared to other caterpillars I see in the yard, their appearance changes a lot as they grow.  So these guys will be fun to watch.

I also saw this tropical checkered-skipper on a squash flower.  This is a volunteer plant, so I’m not even sure what kind of squash it is, it just grew out of some compost I mixed into a raised bed around pepper plants.

I really haven’t been seeing too many butterflies in the yard this year.  And last year, we started getting monarchs in March, though that winter was much milder.  Still, our native species of milkweed have all grown back and are blooming, and we have several milkweed volunteers sprouting in pots (our tropical milkweed, Asclepias currassavica, went to seed last year).

So, while we haven’t yet seen monarchs, I did get a pleasant surprise today in the garden:

Black swallowtail egg on fennel.

This is one of two eastern black swallowtail (Papilio polyxenes asterius) eggs I found nestled in one of our fennel plants.  We went from 2 to 4 plants last year after two large waves of black swallowtails decimated them.

As it has warmed up, more flowers are blooming in the yard.  Right now, a couple of swamp milkweed (Asclepias perennis) plants are in full bloom, and attracting a lot of insect attention.  Below is a fly proving that not just bees and butterflies pollinate.  I also see that milkweed aphids have gotten themselves in a place where it’s difficult to remove them- if I care about keeping the bloom.

My kids had the day off from school, so I spent a little extra time in the garden this morning.  What I found most interesting were a couple of things attached/ in proximity to a spider (Bug #25 from March 3).  One is this leaf with some sort of housing- maybe for eggs? Are they the spiders’?

The web attaches to a mint plant, where I found these eggs (maybe these belong to the spider?):

These two insects were chilling on a milkweed leaf:

I found a couple of different insects on hydrangea leaves:

The afternoon was much more insect friendly, and there was a lot to see.  One was a favorite insect of mine, a blue sweat bee, here pollinating the flowers of one of our fennel plants.

And then, hiding under a tomato leaf, I saw this ladybug:

Spider webs and ant piles have popped up around the yard.  I took a couple of spider pics:

And back on our Meyer lemon tree, ants appeared to be feeding on these insects.  They look different than the previous aphids, but perhaps they’re a different species, or stage of the same species?

Bug 27: Aphids? and ants.

A bumblebee quickly flew by me, but they’ll be easier to capture on camera when I have more flowers in bloom.  Anyhow, something was pollinating our blueberries:

And lastly, our milkweed is starting to re-sprout after dying back in the cold.  After last year’s mild winter, monarchs migrated earlier than we expected.  Our plants weren’t too big yet, and Native Nursery didn’t have many for sale.  We’ll see how it goes this year.

It’s been warmer the last few weeks, but I’ve had to work weekends, I’ve been sick, I’ve been out of town.  So I haven’t been keeping up with bug pics.  But today, I had some (long overdue) work to do in the garden.  I’ll need to start bringing out the DSLR to capture flying insects, and I think that should also be easier when more flowers are in bloom.

aphids and ants on Meyer Lemon flower buds.

Bugs 17 and 18: Aphids and ants on Meyer Lemon flower buds.

A lot of plants are starting to flower in the yard, and our Meyer lemon tree has a couple or three dozen.  I found a few covered with aphids, which of course attract their predators, ants.  I saw a ladybug quickly in the yard, and this is perhaps why.

Bug 19: a winged predator finds aphids.

It’s not the best pic, but this winged predator found a meal on those Meyer lemon buds.  I want those lemons, but I’m also curious to see these buds’ food web if I let them be for a little while.  Hmmm…

This was on the kids’ sand table.  Just as a seasonal note, we can see that here in mid-February we have started getting that pollen coating.

Ants on the compost.

There are so many ant species.  Some will be more obviously different from each other, but I couldn’t say that these are different than what was on the lemon tree.  I found these in a compost pile.

Bug 21: crawling out of the compost.

Bug species 22: on a leaf in my raised bed.

I broke up the soil in one of my raised beds and planted some seeds.  There were a lot more bugs than when I dug in the dirt, for curiosity’s sake, on January 3, our snow day.  I did see the same couple of bug species I saw that day, and a few more that must have dug down deeper for warmth.

I found something kind of interesting when cleaning up on the side of our house.  It looks like a moth cocoon.  Something to keep an eye on over the next couple of weeks, or months.  Some moths overwinter just like the swallowtail butterfly chysalides we have in our kitchen (scroll to January 1).

I also found three more insect species on our Meyer lemon tree.  The more I look, the more I find.  I’ll have to start doing the same with other trees on our property.  Each is an ecosystem unto themselves.

The first insect I saw on the lemon tree is another little green translucent critter.  It’s interesting how many of the creatures I find on it share this trait.

I also found a couple of spiky little guys.  I see them a lot when I look for giant swallowtail caterpillars, which start out kind of spiky looking themselves.

Today I took my search for bugs to our Meyer lemon tree.  This is a potted tree (most of our yard is paved), yielding a handful of lemons a year.  It also hosts a handful of giant swallowtail caterpillars every year.

Surprisingly, I found quite a few bugs on a cold day.

Bugs 7 and 8.

These guys are so small, I didn’t entirely get what I was seeing until later when I zoomed in:

The bigger bug looks like it’s eating the smaller red ones.  Or maybe those are its babies?  And then there is that shell of another bug nearby- maybe its prey?  Or maybe a casualty of the cold.  I saw a few white “bug ghosts:”

And I saw another green translucent insect:

Bug 9.

It looks similar to the other bug, but with white eyes instead of red.  And it kind of looks like it has false eyes on the tip of its abdomen.

I also saw this green translucent spider:

Bug 10.

I wonder what these guys did during the snow and freeze on January 3.  This is what the same leaves looked like that day:

Lastly, I saw these things under one of our coneflower leaves:

Bug 11.

I’ve been seeing a Carolina wren poking around the edges of the yard.  This usually means they’re building a nest- usually in one of our hanging plants.  I’ll have to keep an eye out.  The main food they’ll feed their nestlings is insects- caterpillars, grasshoppers, and even spiders.

Not a day to see a lot of bugs out and about.  However, it did occur to me that bugs have to go somewhere when it’s cold.  So I took a trowel to a corner of the yard where a leaf pile was decomposing into soil.  Here is what I saw:

Bug 5.

This guy scurried back under immediately.  The one below never uncurled- perhaps it was hibernating?

Bug 6.

I was curious to keep digging, but I had other chores and so did the bugs- breaking down leaves to make them soil.  I figure I’ll see plenty more bugs in the dirt when I plant for the spring.

When I was out in the yard today, I saw a yellow rumped warbler- a migratory bird escaping a much colder place than here.

It was a cold day, but I still saw some bugs.  First was this guy, dead in my driveway:

I did see something moving outside:

Little orange milkweed aphids on tropical milkweed (Asclepias currassavica), along with larger black bugs.

Bugs 2 & 3: Little orange milkweed aphids on tropical milkweed (Asclepias currassavica), along with larger black bugs.

I had just cut back my tropical milkweed plants, as we should all do after Thanksgiving.  As we learned in our segment on pollinator gardening, tropical milkweed is not native to our area, and its flowers don’t die back in the winter.  The thing is, when those flowers don’t die off, they carry OE (Ophryocystis elektroscirrha), a parasite that affects monarch butterfly mortality.  That’s why we clip the plants to six inches after Thanksgiving.

These orange milkweed aphids also endanger the monarch caterpillars we like to raise in our yard.  While they don’t affect the caterpillars directly, they can attract monarch predators.

And lastly, we have this in our house:

Bug 4: These are black swallowtail butterfly chrysalides. The two on the outside have hatched.

Last summer, we brought some black swallowtail caterpillars into our house.  They aren’t as predictable as monarchs- they make chrysalides at night and it’s hard to tell when they might hatch.  Here we see three chrysalides.  The two on the outside hatched in November of 2017.  However, if they don’t hatch before it gets cold, swallowtail species overwinter.

If you’re keeping an overwintering chrysalis in your house, be careful not to let it get too hot, or it will hatch (and not thrive outside).  You can keep the outside, just be careful to keep them safe from little critters that might eat them.

I have a lot of footage of these caterpillars.  When I get a shot of one hatching (2 left, and still so unpredictable), I’ll produce a video.

Day 1 total: 4 bug species.

2018 total: 4 bug species.
