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.

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.

Good afternoom Mr. Bugman! Recently I found this lovely pink beetle in the woods of the municipality of Simão Pereira-MG (Brazil) . I’ve never seen equal with this color! Do you who is the beetle? Thanks so much.

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.

Bugman,
We live in west Texas in high (5100 ft.) desert grassland. This week we are being swarmed by small (approx. 1/4″) shiny green beetles. Can you identify them from this picture? Sorry it is not a better one. I am only concerned about them being destructive.
Thanks in advance.

Hi Ray,
As you have indicated, the quality of your image is not optimal, but we believe based on your description that these are Flea Beetles in the tribe Alticini, and we also believe that they might be Apple Flea Beetles,
Altica foliaceae.  According to BugGuide: “In recent years, several outbreaks of this insect have occurred throughout Colorado.”  We will be postdating your submission to go live in the near future while we are away from the office.

Daniel,
Thank you so much for the very quick and very accurate response. Based on the pix accessed from the Bugman link you have certainly nailed it!
Best Regards,
Ray Ornberg

Hello,
Last year I noticed these bugs appearing on a tree in my yard. This year there are MANY MANY MANY of them taking over the tree, and the snow JUST melted.
Cannot figure out what the bug is, or how to help stop it from killing this tree.
Thanks for your help,

Hi Jared,
We don’t know exactly where to begin looking to identify these green Beetles.  We have written to Eric Eaton for assistance.

Hi, Daniel:
Those *aren’t* woodborers.  They are “flea beetles,” probably in the genus Altica, family Chrysomelidae.  Perhaps they overwintered as adults.

I find these bugs only on my Rudbeckia plants, eating but not doing a lot of damage in crevices. If I touch one it drops to the ground. They can fly also.

Dear Bill,
This is some species of Flea Beetle in the tribe Altacini.  Flea Beetles are Leaf Beetles that feed on leaves and flowers, chewing holes as they feed.  They can get very numerous.
