Spotted this one in our kitchen. He seemed to closely match the color and texture of our light grey wall. Any guesses?

Masked Hunter

Masked Hunter

Hi Chris,
Better than a guess, we can assure you with 100% certainty that this is an immature Masked Hunter,
Reduvius personatus, a species of predatory Assassin Bug that has the unique ability to camouflage itself due to the stickiness of its exoskeleton that causes dust and debris to stick to the surface of the insect.  Nearly all reports we have of Masked Hunters are from household interiors, which causes us to believe that they have adapted to a life of cohabitation with humans, and since they will prey upon Bed Bugs and other undesirable household intruders, they are considered beneficial insects, though they might bite if provoked.

Dear Bugman, my name is MK. My husband found this bug last night, 09/01/14, in the evening. It had a very long stinger on the front and kept trying to snack at my husband. We found it in the garage. We Live in a suburb of Philadelphia. Any information would be great, thanks.

Masked Hunter

Masked Hunter

Dear Keri,
This is a beneficial Assassin Bug nymph known as a Masked Hunter, a common name derived from the immature insect’s ability to camouflage itself in its surroundings due to its sticky surface that attracts dust and lint.
  Masked Hunters have adapted to cohabitation with humans and they are often found indoors where they will prey upon Bed Bugs and other unwanted household pests.  All good things come with some drawbacks, and in the case of the Masked Hunter, they should be handled with caution, or better yet, not at all, since they will bite in self defense.

Found this bug on my patio. We live in a state where the “kissing bug” is making the news. I have gotten several conflicting answers and photos on Google are making me even more confused. I just want to know for sure what it is!

Wheel Bug

Wheel Bug

Dear Don’t kiss me!,
Your confusion is understandable because this predatory Wheel Bug is in the same family, the Assassin Bug family Reduviidae, as the Kissing BugWheel Bugs prey upon other insects and they feed using their sharp proboscis that they use to pierce the prey and then suck the fluids from the body.  Kissing Bugs in the genus
Triatoma feed in a similar manner, but they feed on the blood of birds and mammals, including sleeping humans.  The problem with Kissing Bugs is that they can spread Chagras Disease when they bite.  Though there is a chance that carelessly handling a Wheel Bug will result in a painful bite, there is no negative, lasting health problem associated with the bite, merely local swelling and tenderness.

Could you please tell me what the attached picture is? It has a scorpion like tail, and is pretty small. There is a pair of hemostats in the pic for size reference. A friend found it outside his house.

Wondering what this is. My son sent me the photo, so I don’t know if those are mandibles or legs or something else. And I don’t know how many pairs of wings it had.
Looks like a mantis or mantid fly or something like that.
Thanks.

Thread-Legged Assassin Bug

Thread-Legged Assassin Bug

Dear Glen,
This appears to be a Thread-Legged Assassin Bug in the subfamily Emesinae, and the species it most closely resembles on BugGuide is
Stenolemoides arizonensis, a species reported from Arizona and Utah.  We suspect your individual is a different species that is perhaps closely related.  Those raptorial front legs are found in numerous species of unrelated insects that capture prey, including Mantids, Mantispids and Water Scorpions as well as the Thread-Legged Bugs.
