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.

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.

Iron Cross Blister Beetle

Dear JD,
The Blister Beetle family Meloidae includes many brightly colored and unusually patterned members, but the Iron Cross Blister Beetles in the genus
Tegrodera are probably the most remarkable looking.  The coloration is surely aposomatic or warning coloration due to the beetle’s ability to secrete the compound cantharidin that is a known blistering agent to human skin.

Hi Bugman!
Recently, I found this bug walking very unsteadily, falling and rolling, across a hillside in Jackson Hole, Wyoming. Its enormous abdomen was soft to the touch. It was about 2″ long. Is it an ant, beetle or bug from space?! Thanks for your help. Have a Buggy Day!

Oil Beetle

Dear Angela,
This is a female Oil Beetle, a Blister Beetle in the genus
Meloe.  Blister Beetles should be handled with caution as they can secrete a compound, cantharidin, that can cause blistering in human skin.

I found this in the parking lot in Phoenix Arizona in April 2017. I moved it to the flower bed.

Iron Cross Blister Beetle

Dear Alan,
We actually identified your Iron Cross Blister Beetle from just your subject line, though it did help that it was fresh on our mind since just yesterday we posted the first image of an Iron Cross Blister Beetle of the season, also from Phoenix, that had been preyed upon by an unknown predator.
