Caterpillar Identification...Help!

Edinburg, TX

I haven't been able to identify this caterpillar. Was leaning towards some type of hairstreak or blue...but just can't figure it out. Maybe it's a moth. I really don't know...for all I know it's a sawfly larva!!!

Found four of these climbing up on my wooden privacy fence (deep south tip of Texas - smack dab too close to Mexico). I have numerous plants around the area where I found them...only the four o' clocks have been eaten...but not sure by what. Also have passiflora (maypop), aristolochia elegans (calico flower), aristolochia fimbriata (white veined dutchman's pipe), ipomoea ochracea (yellow morning glory), Pride of Barbados trees, sassafras, paw paw, turk's cap hibiscus, milkweed, cestrum parquii, citrus trees and grass. Again...only four o'clocks have been eaten by something.

I recall finding one that look extremely similar to these about two years ago but it was more pink in color with a black head and black forelegs. I found that one on my Mexican Flame Vine and gave it to a fellow butterflier to raise but it died.

Am going to keep these four in a cat cage and see if they will eat...have tossed all kinds of leaves in there :o) Maybe they were on their way to pupating and that's why they were crawling up the wooden fence. Time will tell.

Here's a description: small - one quarter to less than one half of an inch long and a little less than one eighth of inch wide. Light pink to beige in color. The body has chevron like protrusions and each tip has a little hair or something like a tiny spine sticking out of it. They don't sting...or at least I haven't been hurt by handling them so far :o)

I'm no bug expert, but I just had a run-in with spittle bugs and this looks something like the larval form of those. Do you see any spittle on the stems? (Just good to eliminate possiibilities.)

Edinburg, TX

Never heard of a spittle bug...but I will look it up on the net :o)

Uhm...never saw any of those or their spittle on my plants. The spittle bug larvae or nymphs I saw on the net look like bugs...the ones I have truly resemble caterpillars.

Then... never mind! (Please use Rosanne Rosannadanna voice.)

Cat - I have seen something similar on my Pink Gaura plant. It looked like caterpillars. Very, tiny cats. Which means it would have to be a very small butterfly in the adult stage. But I could not be sure. It could have been a larvae of some other bug, too. But ..... they do leave a casing behind. So it looks like they do go into some kind of chrysalis or cocoon or morphing stage. Here is a photo of the empty casings. I guess I will just have to raise the next little critter I find just so I can figure out what it is! I don't have any on my plant currently, but will keep my eyes open. The wasps are terrible this time of year and I'm lucky ANYTHING survives in my yard. Too bad they don't like MW bugs and Cuban Tree frogs. LOL!

Hmmmmm..... Its not in any of my books (FL only) but it looks just like a Hairstreak larva.

Well, they aren't eating anything...and I've tossed a little bit of everything in the vicinity of where I found them. So far they are content to cling to the side of the cat cage...hopefully they will pupate.

Becky...those casings look like the pupa shell (?) of a hover fly. Well, they seem the same shape...but the ones out here are brownish in color. Hover flies love to chomp on aphids. I sat and watched one go from aphid to aphid sucking the juice of each. All that was left was a clear skin and those little black legs!!! :o)

~ Cat

Hmmmm...maybe these pink caterpillars are hover fly larvae...but the only ones I've seen here are green and always on the milkweed in search of aphids. Too late to do it now...but I'll drop some aphids on the cat cage tomorrow morning.

Here's a hover fly larva doing the aphid chomp! You can see the aphid carcasses too!

You just might be correct about that Cat. There "was" aphids on the Gaura before I saw these mystery larvae. Oh good! Another "useful" bug for our gardens!!! :-)

Edinburg, TX

Am still unable to get a fix on these little buggers. They're not eating...or least I can't tell...heck they're so tiny! Still don't see any signs of frass. They are just 'there' - no crawling around...nada. I put in fresh leaves from everything in the legume family I could find...and nudged one a bit. So I know that one is still alive. Still waiting and watching.

I also sent some photos to a Texas entomologist friend of mine...he thought perhaps a younger instar of something from the rekoa family. Is forwarding my photos to a couple of experts in the lep field.

Here's a photo from yesterday...the underside. I nudged one a bit and it rolled over. Seems legarthic and was able to get a photo before it righted itself.

Cat-
I'm waiting to see as well! I like a nice mystery!!

Cat - It certainly does look like a cat of some sort. Too bad no one has been able to ID it for you. That would be helpful in knowing what to feed it. Do you have any Plumbago plants in your yard? I don't know what the Cassius Blue cats look like, but I know they must be small like the little ones you found. Maybe you could try a few leaves of that plant as well?

Sorry I can't come up with an ID for ya. :-(

Edinburg, TX

Still no ID. Bordelon thinks perhaps a beetle larva. Am not sure if these are dead or alive. Will just wait and see what happens. Am too lazy to prowl the net for bug larva photos.

Sorry Cat :(

It's a bummer when you can't find answers to your questions.....

Cat, while looking for an answer id for my cat I found this one that looked like yours, maybe it will help.

It does look the same...good eyes there Josephine! Now how much attention do ya'll pay to the maps that show where they've been sighted?

Adrienne

Josephine, Arlington, TX(Zone 8a)

Yep, I noticed that too, but I thought at least it might put her on the right trail.
I hope so.

I think it might be the Gorgone Checkerspot, this one occurs in Texas, but I could not find a picture of the cat.

Nope...bouyed by your enthusiasm I too searched...and searched....and OK Sorry! Well, I found descriptions of the Cats finally and it doesn't sound like Cat's cat. (Hee,hee) They say it comes in 3 forms and all have black spines...

Onward! :)

Adrienne

oops, here's the link!

Oh well, it was worth a try.

Edinburg, TX

I checked out everyone's links. Still no positive ID. David (Wagner) also says they look like a beetle larvae. Either way, they aren't eating or moving. I've been swapping out every conceivable leaf in my yard as well as a little clump of dirt to no avail.

I haven't found any more in my yard or crawling up the fence. With Quinn, Bordelon and Wagner all leaning towards beetle...am wondering if they are the larvae of all those passion flower flea beetles I had a couple of weeks ago?!

Magpye!!! You're the greatest!!! That first link sure looks like a match.

I ended up putting them into the soil last week as they weren't eating and I didn't want them to die on me...and I have no earthly reason to raise beetles!!! Lawdddddddy!!! I've raised more bug eggs than I care to admit to :o) Alas, the things we must do for not knowing if it's butterfly or bad bug :o)

Looks like a match to me with the Shining Flea Beetle! Good eye and call on that one, Magpye!!!

Lumberton, TX(Zone 8b)

Don't you just love the bug guide? I can't understand why people think it's weird I have it in my "favorites."

Edinburg, TX

You know, I got to thinking...since it's one of those flea beetle larva they must have about from all those dratted passion vine flea beetles I had a few weeks ago. GRRRR!!! Oh well, it raised 4.5 inches yesterday...and 2.5 the day before that...am hoping the zapped all those nasty bugs that live in the soil.

I saw several butterflies hiding out underneath the leaves of various shrubs and trees in my yard...so at least I know they were safe.
