My husband found this bug under his sleeve driving it’s spike into his arm yesterday. It got 4 stings in before it wore a size 9 dunlop volley.
Apparently it packed quite a punch, his arm still red/swollen/itchy 24hrs later. Just curious what bug this is? Doesn’t appear to have wings! Looks like a cross between a hornet & a beetle type bug.

Ground Assassin Bug

Hi Shell,
A little bit of research revealed that this is a female Ground Assassin Bug, Ectomocoris decoratus, which we located on the Geocities Website of Brisbane Insects. Males of the species are winged and fly while the females are winged. Interestingly, we found some of the same photos and illustrations on a Brisbane Insects website with a different URL, but the species was listed as Ectomocoris patricius. We also found a PDF online that states: “Several other assassin bugs bite people in Queensland. … Ectomocoris decoratus, a fast-moving species with winged males and wingless females, is strikingly coloured in blue-black and orange. It occurs under loose bark and may be encountered when gardening or clearing vegetation. Because of its colour and speed, victims of this assassin bug often believe they were stung by a wasp.” We are not exactly sure what a size 9 dunlop volley is, but it sound like it contributed to the squashing evident in your photos. Assassin Bugs, except for a few blood sucking species, are thought of as beneficial predators, so we feel compelled to also tag your posting under Unnecessary Carnage.

Unnecessary? Now that’s being a bit harsh isn’t it? I don’t like to kill unnecessarily (my housemate thinks I’m nuts when I scoop up scorpions and release them into the garden) but if I was getting bitten by something that felt like a wasp, I think I’d do just about anything to be rid of it! Perhaps an “2nd-degree bugslaughter” subcategory? I love your site!

I agree. I try to be tolerant, but if I were being stung or bitten it would be an immediate reaction to end the stinging/biting and prevent future attack. I vote for second degree bug slaughter in self defense.
