Found this beetle (?) dying on my concrete this evening. I live in Kindersley, Saskatchewan. It has a brilliant metallic green body, head of a wasp and dusty purple shell that does not run the full length of it’s body. It has been quite warm and humid lately for August and I was not sure if that is why it was around because I have never seen one before.

Blister Beetle

Blister Beetle

Dear Stacey,
This is a Blister Beetle in the family Meloidae, and we generally prefer a dorsal view for identification purposes, but your description that includes the coloration has us relatively confident that your individual is Nuttall’s Blister Beetle,
Lytta nutalli, which is frequently reported from Canada.  Blister Beetles should not be handled as they often secrete a compound known as cantharidin that is known to cause blistering in human skin.

Dear Bugged out in VA,
This is a Margined Blister Beetle,
Epicauta funebris, and though BugGuide does not indicate any food preferences, we have received other reports of Margined Blister Beetles feeding on the leaves of tomatoes and other vegetables and ornamental garden plants.  In My Kitchen Garden discusses Blister Beetles in organic vegetable gardens.

Hi,
We came across these very striking beetles in dry grassland in eastern Portugal. There were several pairs, apparently biting each other’s tails. They are about two inches long with big black and red abdomens. Please can you tell me what they are?

Red Striped Oil Beetles

Red Striped Oil Beetles

Dear Peter,
You are astute to recognize these Red Striped Oil Beetles,
Berberomeloe majalis, as beetles, as they are not characteristically beetle-like in appearance.  We have several images of this species of Blister Beetle in our archives from Spain as well as Portugal.  We are curious about the behavior they are exhibiting, which you liken to “tail biting” and we can’t help but to wonder if this is some type of courtship behavior.

Dear Daniel,
Thank you very much for the identification.

Hi,
I’m Zumairi from Malaysia. No i’m working with UNAMID in Darfur, Sudan. In my Team Site in Nertiti, there is a bug that call by local as Fesseyah (it’s in arabic actually). According to the local’s, this bug is very dangerous and some of the local says it’s more dangerous than hornet! The colour of this bugs is dark green in the top while it’s abdomen and leg are black. It’ length is about 1 inch.
From local villager, i made to understand that this bug will appear themselves in within and after raining season. But sometimes i find it in whatever season. For your information, geographically, Nertiti is half desert which when the raining season, it will be green everywhere.
I need to know better about this bugs, because i never seen it before in Malaysia. And because, the local’s claim that this this bugs are very poison which can be fatal to human!

Blister Beetle

Blister Beetle

Dear Zumairi,
While we have not been able to identify your beetle to the species level, we can tell you that this is a Blister Beetle in the family Meloidae.  While we believe what you have heard is likely an exaggeration, it is well known that Blister Beetles are capable of secreting a compound known as cantharidin that can cause blistering in human skin.  The legendary aphrodisiac Spanish Fly is made by crushing the bodies of one species of Blister Beetle,
Lytta vesicatoria, and you can get additional information on Encyclopaedia Britannica online.

Oil Beetle

Oil Beetle

Hi Joe,
Congratulations on recognizing that this Oil Beetle in the genus Meloe is actually a beetle, as most requests we received confuse it for a large ant or other insect.  Oil Beetles do not resemble typical beetles as they do not have rigid elytra covering the body and protecting the flight wings.  Oil Beetles are soft bodied beetles with rudimentary elytra.
