Tiger Moth Caterpillar on Water Hyacinth

Dear Phil,
We believe you might be correct.  We found an Invasive.org posting of
Paracles tenuis and the site states:  “Host:  common water hyacinth” and we are presuming the water hyacinth is the invasive species in question.  iNaturalist lists the genus Paracles in South America.  We don’t find the species listed on BugGuide, so this might be a new North American sighting.  Right now we are being thwarted in our research by a glacially slow internet.  We want to browse all Arctiinae caterpillars on BugGuide before we eliminate any native species.

Dear Daniel,
Thanks for the reply and your efforts in this matter. The one I sent you a picture escaped when I wasn’t looking. I found a second smaller one (earlier instar, picture attached) and am continuing to look for others as I am mechanically removing the water hyacinth from the lake as it is an exotic and extremely invasive plant. I will attempt to rear this and any others I find to the adult moth to better secure the identification.
Thanks so much for your help.
Saludos,
Phil

Tiger Moth Caterpillar

Dear Phil,
Good luck eradicating those water hyacinths, an invasive plant species from the Amazon.  We wonder if the caterpillars you found are part of a program to help control the water hyacinths with biological methods.  We look forward to any further updated you can provide, including images of the adult moth.

Tiger Moth Caterpillar

Dear Daniel,
I wouldn’t suspect the caterpillar as a means of control. I have found only 5 in an area of 400 sqft and from what I have seen they only sample a few leaves before moving onto another plant.
In addition to my hand removal of the water hyacinth, the city has sprayed a herbicide twice so far killing (and leaving to rot in place) far more than I could hope to remove by hand.
Bit by bit, but is an aggressive plant and dense to the point of killing all plants below it.
Thanks for your help. I will be back if I am successful in rearing a caterpillar.
Saludos,
Phil Wittman

Dear David,
This is a Banded Tussock Moth Caterpillar,
Halysidota tessellaris, and according to BugGuide:  “Larvae feed on alder, ash, birch, elm, hazel, hickory, oak, poplar, tulip tree, walnut, willow.”  BugGuide does have a posting of an individual found under an apple tree.

Your letter to the bugman:  Bugman,
Found this guy running through our garage. He caught our attention because he was moving fast! Tried to search Google, but can’t find one that looks exactly right. I know there are a lot of different wooly bears, but none of them look quite like this one. The black bands have longer hairs than the yellow. We took this picture, then gently led him outside to the trees.
Thanks!

Giant Leopard Moth Caterpillar

Dear Curious in Georgia,
You are correct there are a lot of different Woolly Bear caterpillars, because according to BugGuide: “265 species in 88 genera listed at nearctica.com” which means there are 265 different caterpillars in the Tiger Moth subfamily.  As you can see from this BugGuide image, this appears to be a Giant Leopard Moth Caterpillar.  According to BugGuide:  “Late instar caterpillar mostly black with tufts of stiff black hairs of equal length radiating around body. Rolls up head to tail when disturbed. When curled, red intersegmental rings visible between the hairs.”

Milkweed Tussock Moth Caterpillar

Dear Sue,
Knowing the plant upon which an insect is found it is often extremely helpful for identification purposes, but not all insects are found on plants, so we don’t have a field for that purpose.  Milkweed is not a “Geographic location” and knowing if something was sighted in Pennsylvania or California or South Africa is also quite helpful, and every bug is found somewhere on the planet, which is why we have a Geographic location field on our submission form.  Having the Geographic location is also of assistance for persons scouring the internet for identification purposes, so we hope you will write back and provide an actual Geographic location so we don’t have to leave that field blank in our posting.  This is a Milkweed Tussock Moth Caterpillar, one of the many species, like the Monarch caterpillar, that depends upon milkweed for survival.  We don’t understand what “Thi dc” means since we could not locate it in the dictionary.

Fall Webworms

Dear Michele,
This appears to be a web full of Fall Webworms,
Hyphantria cunea.   Here is a BugGuide image of the caterpillars that are inside the web.  According to BugGuide:  “About 120 species of hardwood trees have been recorded as larval hosts.  In the north, common hosts include alder, apple, ash, birch, Box-Elder (Acer negundo), cherry, elm, mulberry, poplar, willow.  In the south, common hosts include ash, hickory, maple, mulberry, oak, pecan, poplar, redbud, sweetgum, walnut, willow; preferences for different host plant species appear to be regional and seasonal.”
