Dear Buehler,
Based on this BugGuide image, we believe your Leaf Beetle might be
Calligrapha californica.  According to BugGuide:  “Host plants are Coreopsis, Bidens and Ambrosia – all composites.”  We will be post-dating your submission to go live to our site later in the month when our editorial staff is away on holiday.

Mating Swamp Milkweed Leaf Beetles

Dear Connie,
Do you have any milkweed growing in your garden?  That is the preferred food plant of these mating Swamp Milkweed Leaf Beetles,
Labidomera clivicollis, and you can verify our identification by comparing to this BugGuide image.  According to BugGuide:  “Often overwinter as adults among leaves, e.g. on mullein (Verbascum). Adults mate on or around milkweed. Eggs are cemented to the underside of leaves. Larvae feed on leaves, and drop to ground to pupate.”  According to Bug of the Week:  “Adult beetles are voracious feeders and they quickly removed large slices of the leaves. Leaf protein is translated into batches of eggs within the female beetle. About a week after eggs are laid, rotund orange beetle larvae hatched from these eggs and grazed mightily on my milkweed. Larvae move to the soil to pupate and by September a fresh batch of adult beetles had emerged and colonized the milkweed. Adults of this generation fatten up on milkweed leaves before finding a protected refuge somewhere in my garden to spend the winter.”  We are post-dating your submission to go live to our site later in the month while our editorial staff is away on holiday.

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.

I’m not sure it’s a bug. It looks like suction cup to window. 70° outside, June.

Clavate Tortoise Beetle

Dear Interested mama,
This is a Clavate Tortoise Beetle.  According to BugGuide, the food plants include:  “ground-cherries (
Physalis), Jimsonweed (Datura stramonium), and Solanum spp. (Solanaceae).”

Thank you very much!
In my 57 yrs of being a tomboy running around outside in Southwestern Ohio, I had never seen one…and neither had any of my almost 300 Facebook friends who weighed in. I will look at the info on this creature!
