I had an “assignment” from an entomologist at the California Department of Agriculture to rear a particular species of slug moth (Euclea incisa, not present in California so he can’t do it himself) and document variations in caterpillars from different broods. No problem! I said.

He probably didn’t expect embryonic development updates.

The eggs of this species are completely transparent and flat, so checking in was easy and SO COOL.

Anyways these babes are one of the stinging slug caterpillars, and they don’t have prolegs (?!), check out that last gif. Mom of these ones is in the last photo. They are super tiny, microscope shots are magnified 50x.

Said Californian entomologist is a Good Dude and offered to help me write up the paper without author credit on the babes. I can’t get an entomology job without an entomology degree, but I wonder how many single-author papers I can publish to substitute for one (probably none lol).

Spiny slug baby updates

The purpose of this “experiment” is to see if there are differences in how the caterpillars look between different batches of eggs, but I’m going to go insane keeping track of that here AND on iNat, so here are a bunch of unlabeled random slug babies! Microscope shots are all magnified 20x in this batch.

Arranged from youngest to oldest. They get spinier and stingier as they grow!

Jellypillar!!!!

Look! You can see them without the microscope now!!! And I am totally raising them in a parmesan container, they are too small to keep in anything else.

At their largest, they are about the size of a jelly bean. A… spiny jelly bean. Do not eat.

Spiny Slug Jellypillar Update

He monch

Wheeeeeee!

Save me

It’s warm enough in my house that I am constantly fighting against mold in their little containers, but if they are molting I can’t move them off a moldy leaf. It’s a situation. I upgraded the big batch of them to a salad bin (formerly in a parmesan container). The rest of the babies are in sauce cups.

Wecome to my salad bar!

The worst salad? Or…

the best salad?

They’re so cute save me how are there so many where did they come from

This isn’t even all of them

Some updates!

COCOONS EVERYWHERE

also

@thedaeyoung holy carp yes they do

Last night I was up too late doing emergency caterpillar feeding. I need to switch their enclosure over but I don’t have a clean one and I can’t eat the salad I bought fast enough to move them into that container, and there’s a lot of mold growing at the bottom of this one. I was worried about cocoons getting moldy, feeding leaves to caterpillars, and I accidentally bumped a baby with my finger.

OUCH!

The sting was worse than an io moth caterpillar sting! It wasn’t a very hard bump though, I’m sure a proper sting would be much more painful. Very impressive!

We had tomato plants this year.

Operative word had.

Don’t worry, we didn’t kill them, we put them back on the doomed plants after snapping a photo. They completely stripped two large tomato plants in two days. Honestly kinda impressive.

@nanonaturalist

I love them *kisses the babies*

Reminds me of a situation a lady in my butterfly group had:

Euclea incisa slug moth caterpillars

Top gif: heartbeat in a caterpillar visible before molting
Other gifs: restless caterpillar seeks out a pupation spot (his heartbeat was also visible, though harder to see in the gifs)

They grow so fast!

PS

Here is the cocoon of our restless fellow (and his final poops):

Also, he monch (look at his little bum in the lower right corner!).

The slug moths hide their faces so they will hold their leaves with opposable face flaps that look like giant lips. It’s like if you wore a hoodie laced mostly shut and ate by putting food into the narrow opening of the hood.

This fat girl is lovely. She is a Halysidota sp. Tiger moth. These moths are rare at my house, so I was happy to have a visit from her!

Their common names include the word “tussock moth” (examples are Sycamore Tussock Moth, and Banded Tussock Moth) even though they are not tussock moths, because their caterpillars have the little tufts of fur (they are mimics!):

Notice the above caterpillar is poofy with a couple little tufts at the end? Actual tussock moths (which can sting you!) look like this:

Above: Unidentified Tussock moth caterpillar from Malawi

Left: Definite Tussock Moth from Village Creek State Park, near Beaumont, TX
Right: Southern Tussock Moth from my yard near Austin, TX

These caterpillar are not as all-around poofy, and they also have four tufts on their back near their head (easier to see in the Malawian and Definite caterpillars. The Texan caterpillars are younger, so they don’t have their tufts out on display in full glory like the mature Malawian caterpillar does, but that’s the look our Halysidota baby is going for.

Totally not what I was expecting to see today, almost two months ago I saw a White-Marked Tussock Moth Caterpillar for the first time and had no idea what he was, I wanted to move him from where he was but I knew the spines on his could have been no bueno for me so I left him be. I don’t remember ever seeing the adult Tussock Moth around since they look so mundane, but I’m sure I have, nature is wack

Ah, yes, of course I need to post what the real adult Tussock Moths look like. For example, here is the adult version of the White-marked Tussock Moth (what the above baby turns into):

A handsome man!

Here is one of my Southern Tussock Moth girls all grown up!

And this is an Euproctis sp. Tussock Moth from Malawi. Some of these moths there were super fluffy

Notice how all the Tussock Moths are wearing furry boots? Scroll up a bit and check out our Tiger Moth lady’s legs. Clean shaven! Their body shapes are different as well, but granted, it’s hard to tell with her vibrating so much.

Here’s a different Halysidota sp. I had seen before (a little older and some of the scales have been worn off the wings). Wings are longer, not rounded, the legs don’t look like the moth is riding a furry spider, etc. Not a Tussock moth, despite what they want you to think while they’re caterpillars!

Mystery slug caterpillar! Who is this?! Stay tuned! Updates will be incoming in my @nanonaturalist blog

I investigated and our baby is:

a Yellow-shouldered Slug Moth (yet another stinging slug caterpillar!)

This dramatic fellow was hanging out in the yard for a while last month:

Here is a blurry shot next to my finger to show you how utterly massive these moths get:

truly spectacular

The child grows (I think?)

Resident slug moth expert (over in California) is not sure of my ID, but says whatever I have, hackberry is an undocumented host. Pressure is on to successfully get an adult moth! (Rearing these caterpillars is difficult! They are so small and dry out very easily).
