What’s this bug….please?
Hi Bugman,
We (my son) have found a heap of bugs roaming around the property. We would like to know what they are and what they are doing? They appeared after a large storm event and are just walking around everywhere. My dog also ate some. I will let you know if the dog dies 🙂 Thanks for any info…
Regards
Anthony (and Daemon)

Hi Anthony and Daemon,
These are some species of Roach, but we didn’t recognize them. We found a matching photo on BugGuide, but with no information. We wrote to Eric Eaton, and here is his response: “Depends on where they are. If this image is from Florida, it is probably of the broad Keys roach, Hemiblabera tenebricosa. If they smelled really bad, then maybe they are the stinking cockroach, Eurycotis floridana, found from Mississippi to Florida and Georgia. Without examining the specimens I can’t rule out other possibilities, including nymphs of other roaches, but if they were over 30 mm, then the above two possibilities are best. Eric” We wish you had included a location which is one of the things we request.

mystery roaches
The Mystery roaches on your page are most likely the heaviest roaches in the world. The photographer is almost certainly from Australia if he got these in the wild. These beauties are Macropanesthia rhinoceros, or the Rhinoceros cockroach, in the family Blaberidae. I’ll send you a picture of some specimens I photographed in the LA County Museum (as well as a photo of a specimen of the longest roach Megaloblatta longipennis). These guys are monsters in real life, but live a pretty calm 10 years or more eating Eucalyptus litter.
