Eight Spotted Flea Beetle

Dear Johannes,
This is not a Lady Beetle.  It is a Leaf Beetle in the family Chrysomelidae, and based on the hind legs, we believe it is a Flea Beetle in the tribe Alticini.  It is identified as
Omophoita sp. on the Las Cruces and Wilson Botanical Gardens Costa Rica 2010 Smug Mug site.  It is identified as Omophoita cyanipennis on FlickR and on Jungle Dragon it is called an Eight Spotted Flea Beetle.

Team Biota, volunteers at Mt Rainier would like you to identify a recent find from Steven’s Canyon in Mt Rainier. The beetle was crawling along the rocks in the canyon (70 degrees, sunny) but, did not appear feeding on any plant life. Have never seen this beetle in the Park before.

Unknown Flea Beetle

Dear J. Dreimiller,
This looks to us like a Flea Beetle in the genus
Disonycha, which is well represented on BugGuide, however, BugGuide data does not list any species as being reported in Washington or indeed, the entire Pacific Northwest.  At any rate, the best we can provide at this time is that this is a Leaf Beetle in the family Chrysomelidae.  There are no Leaf Beetles reported on the Mount Rainier National Park Check List, so perhaps you should post your images there to see if you can get a more specific identification.  Please let us know if you learn anything, and perhaps one of our readers will provide a comment with an identification.

Flea Beetle, we believe

Dear S. Frantz,
We believe this is some species of Flea Beetle in the tribe Alticini, a group in the Leaf Beetle family Chrysomelidae.  Your image resembles this image posted to iSpot.

Hello Daniel,
thank you very much for your detailed answer!!!!
It was a big help and I really appreciate your work.
Kind regards from Germany,
Simon Frantz

I occasionally find these in my kitchen they kind of jump and I believe they have wings like ladybugs but I haven’t seen them fly just jump…

Northern Plantain Flea Beetle

Northern Plantain Flea Beetle

Dear Concerned Mama,
Thank you for including a pack of Newport cigarettes for scale, and in our opinion, that pack poses a far greater health threat to all involved than this Flea Beetle does.  We believe we have correctly identified it on BugGuide as the Northern Plantain Flea Beetle,
Dibolia borealis, and based on the size relationship to the pack of cigarettes, the stated 3mm size seems about correct.  According to BugGuide, they feed on:  “Plantago spp. (Plantaginaceae)” and “Larvae are leaf miners of plantains. ”  According to The Herbal Encyclopedia:  “The plant is indigenous to the Mediterranean region and western Asia; but it now grows worldwide … .  To many areas, it is considered a weed.  The herb is an annual that grows to about sixteen inches in height, producing narrow leaves and clusters of tiny whitish-brown flowers.”  Plantain grows in many fields and open areas in the eastern part of North America.  Perhaps you have some plantain near your kitchen which is causing the Flea Beetles to accidentally enter your home.

This was found in May in coastal Connecticut, in our school’s outdoor space. We’d like to know what it is.

Sumac Flea Beetle

Dear Willow Class,
We quickly identified your Leaf Beetle in the family Chrysomelidae as a highly variable Sumac Flea Beetle,
Blepharida rhois, thanks to this BugGuide image.  According to BugGuide, it is also known as a Currant Flea Beetle.

Dear Marcelo,
We are certain this is a Leaf Beetle in the family Chrysomelidae, and we are relatively certain it is a Flea Beetle in the subfamily Alticini.  This is verified on Nature Closeups where a very similar looking Flea Beetle from Brazil is pictured, but not identified to the species level.  Nature and More has a similar image identified as
Homophoita sp.
