Roachsmith Posted October 19, 2007 Share Posted October 19, 2007 My harlequins and s. lateralis get this odd sticky stuff stuff on them sometimes. What is it? Quote Link to comment Share on other sites More sharing options...
Allpet Roaches Posted October 19, 2007 Share Posted October 19, 2007 A number of species have glands at the rear of the abdomen that pruduce a sticky defensive secretion. "African bullet" roaches produce a good amount. I'm not sure if you can find the exact chemical composition (which is likely to vary somewhat by species and even population) but this abstract lists two chemicals found in the secretion of A. hoeveni: Journal abstract for defensive secretion Quote Link to comment Share on other sites More sharing options...

Roachsmith Posted October 23, 2007 Author Share Posted October 23, 2007 Thanks! That's really interesting. I wonder why they were releasing a defensive goo. I hadn't bothered them for a few days when I noticed it. Maybe they were fighting with eachother. I notice my s. lateralis only seem to get when they're hiding in my T tanks but not when they're with the colony. Quote Link to comment Share on other sites More sharing options...
