Mating Red Turnip Beetles

Dear Larry,
Because we quickly recognized these as Leaf Beetles in the family Chrysomelidae, we were able to identify them as mating Red Turnip Beetles,
Entomoscelis americana, on BugGuide.  According to BugGuide:  “occasional pest of canola, rapeseed and mustard in the northern Great Plains; may also damage other crucifer crops (turnips, cabbage). Larvae and adults feed on plants at night.”

Mating Red Turnip Beetles

Thanks for your quick responce. Very interesting – Will let my son-in-law (a canola farmer) know about these as he saw them too although his farm is hunders of miles away

Three Lined Potato Beetle

Dear R. Green,
This looks to us like a Three Lined Potato Beetle,
Lema daturaphila, which is pictured on BugGuide.  There is no mention on BugGuide of stridulation, which is the hissing sound you heard the beetle make by rubbing together parts of its body.  This comment “I remember the first time I heard them squeaking like little birds when I picked them up” appears on another BugGuide posting.

Thank you so much! It does make chirps and squeaks and small hisses. It’s a strange little thing!

Subject:  Identifying bug on tomato leaf
Geographic location of the bug:  Manassas, Va 20112

Your letter to the bugman:  I found several of these bugs eating tiny holes in the leaves of my tomato plants! I’ve never seen them before. Usually we have hornworms, but never these! They seem to use that brown stuff as cover to hide when threatened. They raise it up and cover themselves with it. Google was NO help.

Tortoise Beetle Larva

Dear Christina,
This is the larva of a Tortoise Beetle and it is carrying its own feces which it uses as camouflage.  We believe it might be a Clavate Tortoise Beetle larva, which is pictured on BugGuide.  According to BugGuide, this species feeds on the leaves of:  “ground-cherries (
Physalis), Jimsonweed (Datura stramonium), and Solanum spp. (Solanaceae)” and this is the plant family that includes tomatoes.

Your letter to the bugman:  I found this yellow and black beetle-like bug standing right next to an open banana peel, and the banana was used to make a smoothie. I do not know if the bug came from the banana and if the banana was strangely coloured because I did not make the smoothie. The peel was quite ripe. I caught the bug and put it in a plastic transparent cup. What is the name of the bug and If the bug came from the banana and I drank the smoothie, will I be ok?

Striped Cucumber Beetle

Dear Michael,
This is a Striped Cucumber Beetle, and according to BugGuide:  “The most important hosts, perhaps the only larval hosts, are Cucurbitaceae.”  We don’t know why it was on the banana.

Your letter to the bugman:  Dear Bugman,
I found this beautiful beetle in the rainforest of the Tambopata reserve in Peru. On the web I found similar ones named Pleasing fungus beetle. But I did not find this specific one. Can you help to identify it?

Leaf Beetle

Dear Gerhard,
Though we have not had any luck with a species identification, we can tell you this stunning beetle is a Leaf Beetle in the family Chrysomelidae.  We are confident we (or one of our readers) will be able to provide a more specific identification soon.

Leaf Beetle

Dear Daniel,
thank you very much, lets see, if someone has additional information.
All the best and thanks for your help again.

Update:  July 1, 2019
Thanks to a comment from Cesar Crash, we are confident this is Platyphora princeps.  The images on PicClick are of dead specimens and they lack the bright colors, but they appear to be the correct species.

Passionflower Flea Beetle stalked by Jumping Spider

Dear C. Abner,
We are amused at your image of a Passionflower Flea Beetle being stalked by a Jumping Spider.  According to BugGuide:  “Larvae and adults freq. found on Passionflower (
Passiflora).”

Haha!!  Yeah, the spider wasn’t there when I went to take the picture.  He jumped out last second and did a ‘photobomb’!  And then went back to his hiding spot under the rail!
Thank you so much for the info!  You’re welcome to use my photos if you’d like.
