Spotted Blister Beetle

Dear Shay,
We are confident we have correctly identified your Spotted Blister Beetle,
Epicauta maculata, thanks to this BugGuide image.  Though BugGuide does not report any sightings from Idaho, there are sightings from nearby Montana and Wyoming.  Blister Beetles should be handled with extreme caution, or even better, not handled, because contact with the cantharidin that many species secrete can cause blistering in human skin.

Blister Beetle

Dear No,
This is a Blister Beetle in the family Meloidae, possibly
Mylabris pustulata based on images posted to Encyclopedia of Life where it states:  “Mylabris pustulata is a species of blister beetle belonging to the Meloidae family found in South Asia. Adults feed mainly on flowers from a wide range of plant families. The first larval instar is an active triungulin form that is a predator of soft insects such as aphids. While the young are often beneficial to crops by suppressing other plant feeders, the adults can be a problem when present in large numbers. Flower feeding leads to lower yield and this can be a problem in some leguminous crops. They are however easily controlled by manual collection.”

I’m new to gardening. So far I’ve been able to identify the pests and beneficials in my garden. However, I’ve failed to identify this bug on any garden pest websites or other picture databases of bugs. Please help it appears these guys are eating on my tomato plants and I’d like to find out what they are so I can use natural means of controlling them.

Subject: Shiny blue 3-segmented in Hungary
Location: Southern Hungary

Hello,
I have recently moved to Hungary and am enjoying exploring and identifying some of the bug life with my children. I was unable to ID this one.
It is quite shiny, almost metallic in the sun. It appears to have 3 segments.
My initial thought was some sort of Cuckoo Wasp but it’s so large, and honestly looks more like an ant. I found 3 of them in a day. Each was alone, all in soft soil alongside a walking path in a deciduous forest. Sometime in mid April.

Hi,
Not sure if you’re interested in this but thought I’d show you an Oil Beetle I found today. I had no idea what it was but thanks to the wonders of Google and your site I think i’ve got the right name.

Oil Beetle

Dear Bill,
Thanks so much for sending in your image of your Scottish Oil Beetle.  We don’t know how many species in the genus Meloe are found in the UK, but
Meloe proscarabeus is mentioned on UK Safari where it states:  “When alarmed, the adult oil beetles can release a foul smelling oil – hence the name.”  There does appear to be a secretion on the palm of your hand.  According to Bug Life:  ” There are five species of oil beetles in the UK, the Black oil beetle (Meloe proscarabaeus), the Violet oil beetle (Meloe violaceus), the Short-necked oil beetle (Meloe brevicollis), the Rugged oil beetle (Meloe rugosus) and the Mediterranean oil beetle (Meloe mediterraneus).  The first three can be found in the spring and we need your help to monitor their distribution to aid our conservation work.”  We would encourage you to post your sighting there.
