Jagged Ambush Bug

Dear Kathy,
Jagged Ambush Bugs like the one in your image often wait concealed on blossoms as unaware pollinating insects fall prey into their raptorial grasp.

Hi! Thanks for offering this service.
This bug was found in Indianapolis in June in my backyard. I was watering some milkweed and coneflower and the bug landed on my leg.
I put the little guy in a Petrie dish and she/he used its front two little arms like clubs, almost dragging them across the dish. The other 4 legs operated normally.
Lastly, the body is green but the back is black/brown and the wings fold to create a kind of ‘t’.

Ambush Bug

Dear John,
This is a predatory Ambush Bug.  Most images of Ambush Bugs on our site were taken on blossoms where the Ambush Bug waits to ambush its prey.

over the last few days there have been multiple occurrences of these black/dark brown bugs in my home. I have seen one near the bathroom on two separate occasions, and tonight one flew into a table lamp in the living room. I have just been catching them and letting them loose outside, but my girlfriend is worried they may be cockroaches, although I don’t think they are. I am concerned bc our cats are trying to eat them, so I would like to make sure they aren’t any danger to them.

Masked Hunter

Dear Madelynn,
This is a Masked Hunter, a predatory Assassin Bug that has adapted to living with humans.  The immature Masked Hunters have a sticky exoskeleton that attracts debris, effectively masking the insect so it is camouflaged in its environment.  Handle Masked Hunters with caution.  They might bite.

Hi! My friend in Ogden, Ut found this wee monster making a meal of her bees.
We can’t find a similar looking critter anywhere on Google, so I realize it could be a juvenile of some species or other, but…we’re stymied.

Bee Assassin: Apiomerus montanus

Dear Philina,
This is an Assassin Bug in the genus
Apiomerus, a group commonly called the Bee Assassins.  We are relatively confident your individual is Apiomeris montanus based on this BugGuide image.  Is Ogden at a high elevation?  The habitat, according to BugGuide is:  “Mountainous regions. Collected from 1075-2896 meters. “

Daniel, thank you! Ogden is at about 4800 feet, and right up in the foothills. So yeah, mountainous is a good word.
Any suggestions for my friends whose apiary is under attack?
Natural repellents?
Thank you!

Sorry Philina, we do not offer extermination advice.

Oh, she doesn’t want to exterminate them, just keep them away from her hives. I was thinking more like, if she sprinkled cayenne pepper around the hives, they don’t like it and won’t come by it, sort of ideas. But now that i read they can fly that’s not really useful anyway.
Thanks for the help in identifying it though. We were all making good guesses, but couldn’t find any matching pictures.

Masked Hunter

Dear Concerned Mama,
This is an adult Masked Hunter, and it is classified with Kissing Bugs in the Assassin Bug family.  According to BugGuide:  “Can inflict a painful bite but does not feed on blood, and does not transmit diseases.  Introduced from Europe.” You may have already encountered Masked Hunter nymphs in your home.  Their sticky exoskeleton attracts dust and debris which effectively camouflages them in their environment.

Masked Hunter

Dear Mary,
This looks to us like an adult Masked Hunter, a species of Assassin Bug that has adapted to living indoors with humans.  We generally get images of “masked” immature Masked Hunters that are covered with debris as a means of camouflage.  You can verify our identification by viewing this BugGuide image.  According to BugGuide:  “Can inflict a painful bite but does not feed on blood, and does not transmit diseases.  Introduced from Europe.”
