the_cream_man Posted May 27 Report Share Posted May 27 I was feeding my D.grantii the other night and one of them had it's head at the surface when I opened the tub. I looked at it and a black liquid started being up from it's mouth. Is this a deterrent? Kinda freaked me out tbh Quote Link to comment Share on other sites More sharing options...
Oak Posted May 27 Report Share Posted May 27 It is a deterrent. I noticed this behavior only from Dynastes grantii so far. Quote Link to comment Share on other sites More sharing options...
Goliathus Posted May 27 Report Share Posted May 27 Adult Dynastes do it as well. Regurgitating liquified gut contents when disturbed is also a well known behavior in many Orthoptera, especially short-horned grasshoppers (Acrididae). Presumably, the fluid is foul-tasting to predators. Quote Link to comment Share on other sites More sharing options...
the_cream_man Posted May 29 Author Report Share Posted May 29 @Oak & @Goliathus thanks, I'm glad others can confirm this behavior-- really freaked me out. Would really be freaked if an adult did that to me 😰 Quote Link to comment Share on other sites More sharing options...
