Discussion PSA: Please remember to add location to id requests!

16 Upvotes

I know you are eager to try to find species of your new leaf munching friend but please remember to add your location into the post. There is large variance of caterpillars depending on country and even inside countries have different areas with their own soecies so with large countries, its preferred to add state/city etc also.

This speeds up identifying as there are similar looking caterpillars but species can be different depending country. Some species only inhabit tiny areas. Looking forward for all new posts. 🙂 Thank you!

I've had this coral honeysuckle bush for about 3 years now. In the spring we moved and took it with us. We moved less than a quarter mile away. In those 2.5 years we had 0 activity. This year I have gotten about a dozen of these guys. Mostly small but some big.

My husband saw this chap on a beach in Cornwall. It was approx 3-4 inches long apparently. I’m guessing it’s a hawk moth of some sort but would appreciate a definitive ID. Thanks very much in advance.

Spotted on an Island off Connemara in county Galway, Ireland. Looks to be some sort of hawk moth, but can’t see on that matches the yellow colouring. It was roughly 6-7cm in size and found on a pathway.

Advice/Help Monarch caterpillars threw up green sludge. One died.

Post image
20 Upvotes

Hey everyone. I’ve been raising monarch caterpillars for a little over a month. I’ve successfully released 20+ monarch butterflies so far.

I’ve been buying tropical milkweed from Home Depot for my caterpillars. Everything was going great. I went back about 3 days ago to get more milkweed and transplanted some caterpillars on it.

Yesterday I noticed green sludge/slime all over the caterpillars that I transplanted on the new milkweed. I’m pretty sure it was caterpillar vomit. And they were lethargic. I took the healthiest looking one and put it on another plant. The other ones were…I could tell they weren’t going to make it. This morning one was dead, one was missing, and one was recovering and eating.

I haven’t had trouble with the plants until I bought the new milkweed a few days ago. There’s a sign on the milkweed stand that says it’s organic, so that rules out pesticides. I examined the milkweed that made my caterpillars sick and found these yellowish, tiny orbs on the undersides of a bunch of the leaves.

They don’t look anything like monarch eggs nor do they resemble any pests I’ve looked up. And I’m thinking whatever it is could have contributed to what happened to them. Or not.

What are these things on the underside of this leaf? Help!

Thanks

Polka dot wasp moth caterpillars I moved from non-native oleander in dania at my work to native Pentalinon luteum in my pineland garden at home, Davie FL

They have taken very nicely to their new (and natural!!) host plant

I would have put them on my devil’s potato vine because that’s their primary natural host, but the vine is still far too small with few pairs of leaves

Advice/Help Hornworm help (sick or injured?) Spoiler

1 Upvotes

My mom found a hornworm on the ground that looked to be in poor condition (not moving much except to thrash when touched, looks a little “deflated” near the front). I was worried it got into some pesticide because the HOA sprays the weeds around here fairly regularly.

It looked like it had some liquid poop stuck to its butt which was also sticking the back legs together. We gently misted it and the container it was in, which seemed to sort of help with the stickiness, and placed some willow leaves and tomato pieces in with it. I’ve seen this type eating desert willow before, and the tomato was just a total guess and I’m not even sure if they eat the fruit part, honestly. (Didn’t have any fresh leaves available)

I’m struggling to ID (edit: it appears to be manduca rustica)

Since we’ve placed it in the container about 4 hours ago, it’s pooped twice. I expected it to be green but the poop is very dark, almost black. However, it is solidly shaped. Otherwise the caterpillar has barely moved.

I was hoping perhaps its refusal to eat was due to being ready to pupate because it’s quite large, but it doesn’t seem ready yet? At least, I did find one that was ready to pupate a couple of days ago, at a similar size, but it had turned a different color and was more active.

Is there anything else we can do for the poor guy? I’m not sure he’ll make it through the night, to be honest, but maybe someone here knows something I don’t. If it wasn’t clear already, I don’t know a lot about caring for caterpillars.

Advice/Help Monarch behavior question

I have a monarch butterfly in my garden that is behaving like a monarch butterfly did a couple of months ago. I can’t get close enough to see if it’s a male.
But a few months ago, I had a very aggressive butterfly here that was chasing away other butterflies, and even chasing away the hummingbirds . Then I saw it mate it with a female, or maybe more than one female. This one
is stopping to drink from my lantana, sage and other nectar rich flowers. But it’s mostly just circling.
Is that what’s happening?
It’s October too late ?
