Your letter to the bugman:  I have seen these in the months of June and July on blooming mountain lupines in the Little Belt and the Castle Mountains. I would like to know what kind of beetle these are?

Leaf Beetles, we believe

Dear David,
The image of a solitary beetle on a blossom is definitely a Blister Beetle in the family Meloidae, but we are uncertain of the species.  The other image showing an aggregation of Beetles appears to be a different species.  Can you clarify any information on these two images, especially the group of beetles.  Were they found aggregating as the image depicts?  Here is a BugGuide image of 
Linsleya sphaericollis that resembles the Blister Beetle in your image of a solitary individual, but again, we cannot verify the species.

Leaf Beetles

Hi, thank you for the quick response.  The aggregation of beetles I thought was the same, as the solitary beetle. But on closer inspection, I see differences in body shape. The plant is not mountain lupine. I realized I had grabbed two images taken at different places. The group is later in the summer.  Each beetle isn’t very big. Maybe 3/8 to 1/2 inch. I am looking at the plant they are eating it isn’t milkweed or dogbane.  Here are more photos. They are part of the group. I isolated out a few of the beetles. They are mostly in focus. The photo was taken in July or August in Montana in the mountains.
Cheers

David

Leaf Beetles

Dear David,
Your newly submitted images appear to be the same beetles that were in your original aggregation image, and we believe they are Leaf Beetles, possibly Flea Beetles from the genus
Altica like the ones in this BugGuide image.

False Potato Beetle

Dear Krista,
Thanks for submitting your image after providing several comments on a Ten Lined June Beetle posting.  Interestingly, we had almost this same case of mistaken identity with our good friend Monique who believed she saw a Ten Lined June Beetle in France.  Your beetle is a considerably smaller False Colorado Beetle, which can be distinguished from an actual, related Colorado Potato Beetle, because, according to BugGuide, the former has:  “a brown stripe at the center of each elytron (wing cover) and on the inner edge of each elytron (where they meet down the middle) distinguish this species.”  The Ten Lined June Beetle is longer, wider and considerably heavier than either of the Potato Beetles.

Your letter to the bugman:  This lovely was resting on a water hyacinth in my garden. The iPhone pic doesn’t do its color justice – it was a bright metallic gold.  I’m guessing it’s a leaf or a tortoise beetle, but I haven’t been able to find any matches online.  Any ideas?
(Plus, it’s a really cool photo and I wanted to share it.)

Tortoise Beetle, we believe

Dear dr sunsets,
This is a Leaf Beetle in the family Chrysomelidae, and we believe it is a Tortoise Beetle in the tribe Cassidini, but we didn’t read your submission that carefully, and we thought you took this image in The Netherlands, so we did not find any matching images.  We will attempt a new search of Caribbean species.  A quick search turned up no matches.  Perhaps one of our readers will have better luck.

Wow, thanks so much for your quick reply!

Your letter to the bugman:  This beautiful beetle landed on me while walking in a mixed, mature forest near an open area that had been clearcut logged a couple years back. It’s gorgeous markings were very metallic and it happily explored my hand for awhile allowing us a great look. Neither my husband nor I had ever seen one before. Well! Wouldn’t ya know it that a week later at a beach on the Southern shore of Lake Superior there was another, though this individual did not seem as brilliant as the first.
Would love to know what it is and thank you very much for this fabulous site which my sister discovered and recommended.

Leaf Beetle: Calligrapha species

Dear Critter-Loving Lady,
This is a Leaf Beetle in the genus
Calligrapha, and there are many similar looking species.  Your individual might be Calligrapha rhoda which is picture on BugGuide where it states:  “host: Corylus (hazel).”

Leaf Beetle: Calligrapha species

Hello Daniel Marlos,
Wow! Your reply is about a zillion times faster than anticipated and very much appreciated. Thank you. Can’t wait to explore the data on this genus as well as peruse your excellent site. Truly a treasure it is.
By the way, it made me extremely happy to see What’s That Bug site posts that it is NOT in support of extermination. I’m working very hard to undo any sneaky, lingering crappy mindsets I have about all insects around me. Learning to appreciate, admire and even love their presence has deeply enriched my day to day experiences, though I still struggle when a group happily gangs up in a forage-fest on something I’m also hoping to eat. A lecture of, “Hey! Let’s share everyone!” has so far been pretty ineffectual.
Have a most wonderful day.
Critter-Loving Lady

Your letter to the bugman:  My friend found this beautiful bug on his rain gutter downspout this week. It almost looks like a china pattern…  can you please help us identify it?  I’ve been unable to find any similar pictures online so far. Thank you.

Leaf Beetle

Dear Amy,
This is not a Shield Bug.  It is a Leaf Beetle in the genus
Calligrapha.  We suspect it is the wide ranging and considerably variable Common Willow Calligrapha pictured on BugGuide.

Your letter to the bugman:  We found this spectacular beetle on Stoney Man Mountain (~3800 ft elevation) in Shenandoah National Park. We thought it might be a rare type of ladybug/ladybird; but we have been unable to find this pattern (with black, red, and shiny gold outlining) in any guide. Can you help us ID this gorgeous beetle?

Leaf Beetle

Dear Adam & Caleb,
This is not a Lady Beetle.  It is a Leaf Beetle in the genus
Calligrapha, possibly Calligrapha spiraea based on this BugGuide image. 

Thank you!  That looks like the perfect identification!
Best,
Adam
