Your letter to the bugman:  We were moving things in our mother’s unfinished basement preparing for her home to be sold and this frisky fella was hiding in a cardboard box. Scoots around pretty fast and reminded us of a crab with how it walked. It looks “dusty” and at first we thought it was some sort of spider, but only has six legs, not 8 and has antennas. Is this something to be worried about in her home? Are they poisonous, do they bite, what attracts them?? So far we only found one but he’s a really cool looking fella!

Masked Hunter

Dear Stacy,
This is a Masked Hunter, an immature Assassin Bug in the species 
Reduvius personatus that has a sticky exoskeleton.  All manner of dust and debris sticks to the insect, effectively masking it in its surroundings in an interesting example of adaptive camouflage.  According to BugGuide:  “Nymphs cover themselves with dust, lint, sand, and other debris which usually matches the color of their immediate surroundings and makes the nymphs difficult to detect.”

Your letter to the bugman:  Hey so this bug bit me an idk if it’s A Black Corsair or a kissing bug
How you want your letter signed:  Not sure

Black Corsair

We just created another new posting with a Black Corsair, and that is what you have encountered.  This is not a Kissing Bug.  You have confused the two which is understandable as both are Assassin Bugs and both will bite, but according to BugGuide, unlike the Kissing Bug which spreads Chagas Disease, the Black Corsair:  “Can inflict a painful bite but does not feed on blood and does not transmit diseases.”

Your letter to the bugman:  Found three of these in my house, was looking online to see if they were a native species but the only bugs I could find that resembled them were native to the southern states (texas, arizona etc)

Black Corsair

This is a Black Corsair, Melanolestes picipes, and it is a native species, but Washington does not have any sightings according to BugGuide, however, that is only an indication that there have not been any submissions from Washington.  Exercise caution with the Black Corsair.  It can bite and the bite is reported to be painful.  According to BugEric:  “Be careful that you don’t ever mindlessly swat one of these insects if it lands on you.  the defensive bites of assassin bugs in general are excruciating, and the odds of being bitten go up when the Black Corsair comes to town.  Because they are attracted to lights, and run and fly with great speed and afility, the males may find their way indoors.”  According to BugGuide:  “Can inflict a painful bite but does not feed on blood and does not transmit diseases.”

Newly Hatched Leaf Footed Bugs

Dear John,
These are not Pseudoscorpions.  They are newly hatched True Bugs.  The empty egg cases can be seen at the edge of the tape measure.  We suspect they are in the family Coreidae, the Leaf Footed Bugs or Big Legged Bugs.  Our Brazilian colleague Cesar Crash believes they are Assassin Bugs.

Your letter to the bugman:  I found This tiny bug in my bathroom, it’s a bit longer than a small ant. I initially thought was a spider, but it appears to be an insect possibly as it has 6 appendages, it walks on 4 and has two grabbers like spraying mantis. What is it?

Tread Legged Bug

Dear David,
This is an Assassin Bug in the subfamily Emesinae, the Thread Legged Bugs and there are several species on BugGuide listed in California, but the best we are able to provide with assurance is the subfamily identification.  BugGuide does support your observation by stating:  “Unlike walking-sticks and some dipterans they mimic, the Emesinae walk on the rear four legs — the front legs are modified for grasping prey.” Assassin Bugs are predators and some species are know to bite humans, so they should be handled with caution.

Thanks Daniel, I suspected it was possibly an assassin bug, but it didn’t look at all like the big ones that carry Chagas’ disease.

Spiny Assassin Bug Nymph

Dear ahardy,
This is not a Mantis, but your mistake is understandable as both Mantids and this Spiny Assassin Bug nymph from the genus
Sinea both have raptoreal front legs they use to grasp prey.  Handle with caution.  Assassin Bugs might bite if carelessly handled.
