I’m wondering what type these are taking over my plants! There are probably 100 on one bush.

Genista Broom Caterpillars

Dear Anna,
You can compare your image to this BugGuide image to verify that you are being troubled by Genista Broom Caterpillars,
Uresiphita reversalis, a species sometimes called a Sophora Worm.  Genista Broom Caterpillars feed on leguminous plants.

Carrot Seed Caterpillar on Dill

We have not had any luck identifying your caterpillar.  The only caterpillars we can find associated with dill in Eastern North America is the Black Swallowtail Caterpillar, and your caterpillar is most definitely not a Black Swallowtail Caterpillar.  Your caterpillar does remind us of the Sophora Worm, but they feed on legumes and dill is not a legume.  Perhaps one of our readers will recognize this caterpillar.

Ive talked to another girl I know and she said its called a purple carrot seed caterpillar/moth.  Ever heard of those?

The Carrot Seed Caterpillar pictured on BugGuide does appear correct.  According to BugGuide:  “The larvae feed on umbellifers, particularly wild carrot” and “‘Recently introduced into North America (first specimen reported from 2002) and now known from Illinois, Indiana, Michigan and Wisconsin’. * (information from – Moth Photographers Group). “

I have several tent nests on the Prairie Dogbane (I believe this is the plant, though my MIL says it’s milkweed) growing in my front yard. These are silky nests on the leaf ends of the plants, and they aren’t found on any other plant species in my flowerbeds. The eggs are tiny and dark, almost black, and the larvae are less than an inch in length, orangish in color, with black spots and no hairs. The larvae may still be immature, though there were several sizes in the nests, and these were the largest I found. Can you identify these insects? Are they beneficial or pests? Thanks for your help!

Dogbane Saucrobotys Caterpillars

Dogbane Saucrobotys Caterpillars

Dear Val,
Thanks for providing the name of the food plant, because we didn’t have a clue about the identity of these caterpillars, but we quickly identified them as Dogbane Saucrobotys Caterpillars,
Saucrobotys futilalis, thanks to this image on BugGuide.  According to BugGuide:  “Caterpillar feeds on dogbane, Apocynum species, including Apocynum cannabinum (Indian Hemp), and on milkweeds, Asclepias species, including butterfly weed, Asclepias tuberosa (Maryland Moths). Larvae make conspicuous silk nests on their host plant.”

Hi there,
This is just a reiteration of an earlier question you got that I also saw. I live about an hour north of Tampa, FL, and saw the same larvae as the one in this photo:
https://www.whatsthatbug.com/2014/02/11/orange-larvae-caterpillarf-sawflies/
I thought my photos would be a good complement to the others already provided and may help someone else seeking the ID of this bug. The larva moved quickly, but I did not find what they were feeding on. I found them in the vicinity of our cactus garden, but I found they were more on a piece of driftwood than any of the cacti. I only saw them crawling around at that one specific time and don’t believe I caught sight of any others in our garden after that encounter (but there were plenty during that encounter, crawling around quickly but aimlessly). Unfortunately, I did not get a photo of their prolegs that I can find.
This was in late January of last year (so approximately 1 year ago). I haven’t seen anything this year so far, though!
Thanks, and good luck fighting the good fight!

Sawfly Larva

Tropical Cactus Moth Caterpillar

Dear Fellow Buglover,
Thanks for providing additional images similar to those from a previous posting.  We believe both examples are Sawfly Larvae, and both look very similar to this BugGuide image identified as being in the genus
Arge.  Can you provide any information on the size of the individual?

Carpenter Moth Caterpillar
Because of a new query we just received that we are researching, we now believe both this and an additional posting in our archives are Carpenter Moth larvae in the family Cossidae, but we are uncertain of the species since the larvae do not look like any posted to BugGuide., but they do resemble what has tentatively been identified as the Carpenter Moth Caterpillar Macrocassus toluminus from South Africa.

Update:  Tropical Cactus Borers
Ed. Note: 
The following is a comment from Cesar Crash.
Those look like Lepidoptera. Found on a cactus garden, may be the cactus moth: https://www.ipmimages.org/browse/detail.cfm?imgnum=5015058 aka Tropical Cactus Borer https://bugguide.net/node/view/78959/bgpage

Thanks so much Cesar.  The mystery is finally solved.  Here is a nice BugGuide image of the caterpillar.  According to BugGuide:  “Imported to the Caribbean to control prickly pear cacti; arrived in the U.S. naturally or in cargo imported from the Caribbean (Johnson and Stiling 1998). Widely dist. in southern FL, spreading east along the Gulf Coast to New Orleans and north along the Atlantic Coast to SC.”  BugGuide also has this interesting statement:  “The moth has become a pest in se US.   This South American moth was introduced into Australia to control cacti, which are not native to that continent and which were becoming a very serious pest. It was so successful that memorials and monuments to it have been erected by grateful citizens there.”

All of a sudden these showed up and within a week how do I get rid of them. In a week they killed a very healthy Spanish broom bush.

Genista Broom Moth Caterpillar

This is a Sophora Worm or Genista Broom Moth Caterpillar, Uresiphita reversalis, and a year ago they defoliated a Golden Chain Tree in our own Los Angeles garden.  The leaves grew back and the tree survived.
