Lucanus Posted November 18, 2012 Report Share Posted November 18, 2012 I was going to wait little longer to post about this but I just couldn't wait. After checking my 1 Dynastes tityus larva, 2 Dynastes grantii X tityus hybrids, and 1 Dynastes grantii larva for three months (it took me sooooo long!), I was able to observe one of the hybrid larva using its body fluid to build the pupal cell Here is my Youtube channel with videos of larva building pupal cell. http://www.youtube.com/user/TheAlanJeon?feature=mhee In the beginning ( ), larva started to compress the substrate around it to form the frame of the pupal cell. Larva does this buy pushing the substrates around it with its head. Orin was right about this part. But unlike what Orin said, larva began to release body fluids after the basic outline of pupal cell was formed -about 18 hours after I first observed the larva building pupal cell- . ( - you can see the fluid on the wall of the container and you can also see that part of the wall of pupal cell is wet) released clear fluid out of its anus. This made the surrounding substrates wet and easy to cluster. After that, larva began to use this wet substrates to finish building the pupal cell. But unlike what I expacted, larva hasn't used its feces much than I expacted (Hardly none). The specimen hasn't become prepupa yet so I am still observing to see what the larva will do with that feces. In Trypoxylus dichotomus, larva released liquid like feces on the walls of pupal cell which helped smoothing out the wall of the pupal cell (but they didn't seem to use the fluid like the hybrids so I guess T. dichotomus pupal cell is weaker than D. tityus because they don't use fluids to build the pupal cell. I can go into further but I have SAT coming in like two weeks so I'll wait till I take SAT. Quote Link to comment Share on other sites More sharing options...
