Orange/Black Beetle/Hornet ? NSW
Sat, Dec 13, 2008 at 3:57 PM
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

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.

South FL: Wasp-ish w/ proboscis, Black, Red, White Spots
Sun, Dec 7, 2008 at 10:17 PM
I just came across your website the other day and low and behold I head out to garden this afternoon and see this little guy in my backyard! I’ve lived in West Broward (South Florida) all my life and never seen one like this…
It was lying on my pool deck and seems to be on his (or hers) last limbs. 🙁 I placed the little guy on a plant after I took these pics.
It has two pairs of wings (which is reminiscent of a wasp, but it also has a proboscis, and very, very long antennae and legs.
What is this South Florida creature? Is it even from here?

Milkweed Assassin Bug

Milkweed Assassin Bug

Hi Sunny,
You have found an Assassin Bug and we believe it is a Milkweed Assassin Bug, Zelus longipes. Assassin Bugs are predators, and though most species do not bite humans unprovoked, if they are carelessly handled, they can deliver a painful bite.  The Milkweed Assassin Bug is a local species for your location.

Greeen asssassination with wings

I found this bug on my screen that’s on my window. I didn’t want to have this bug roaming around my house before i knew what it was so i close the window and as soon as i did that it hiked up its front legs like a mantis. I saw on your page that it might be an assassin bug? So what is this creature and what does it do?

Hi G-Money,
Yes, this is an Assassin Bug.  It is difficult to tell from the angle, but we suspect it is in the genus Zelus.

Northern Lower Peninsula Michigan 11/15/2008 Friendly Bug
Sat, Nov 15, 2008 at 2:19 PM
Hi, Love the site! This curious (seemingly) friendly little fellow is the second one I have found in my house in the past week (Nov. 8-15). The first one was all green and they were both found around my computer. The first one I took outside but the weather cooled down and I couldn’t leave this one outside (he stood motionless in the same spot for an hour), so I brought him back in and I have been keeping him in a jar…he doesn’t seem to mind too much. The first photo is a side view and I included a dime in the picture for comparison. The second photo is a top view . I’d just like to know what he is so I can get him some food for the winter before it snows…I’ll let him go in the spring. He is rather interesting to watch. Keep up the great work!
Thank you! Kim

Hi Kim,
This looks like an immature Assassin Bug in the genus Zelus to us.

Unusual behavior?

I found this guy on my writing table, and was surprised to see what he was doing. Is this their normal way of preparing for winter?
BugGuide.net indicates it is an Orange Assassin Bug, Pselliopus. We are in Western Maryland. Second and third photos are slightly clearer, and less interesting. ;^)

Hi MsMuffet,
Thanks for the wonderful image of a Pselliopus Assassin Bug.  Many Hemipterans, including Boxelder Bugs, Western Conifer Seed Bugs, and Stink Bugs seek shelter indoors when winter approaches.  It seems the same behavior may be true of some Assassin Bugs as well.

Bug Love Meets Where’s Waldo

My son Sam took this picture of what he thought was an assassin bug on a flower. Later when we looked back at it we noticed that it was actually two bugs mating. If you can zoom in it’s really a pretty amazing picture. We are wondering now if they are assassin bugs since they don’t seem much like the others on this site. In any case, it’s one for your Bug Love. Any ideas? Thanks, as always, for your great great site!

Mating Ambush Bugs

Mating Ambush Bugs

Hi Sam and Daddy Jim,
Though they are sometimes mistaken for Assassin Bugs, Ambush Bugs are in a different family, Phymatidae.  Your pair are Jagged Ambush Bugs in the genus Phymata, and you can see more images on BugGuide.
