On a positive note . . .
This could be a fun story. Of course, it's been done with The Fly in 1958 and in 1986.
Star Trek TNG had an episode with a similar theme with the crew members "devolving." (Stupid premise, if you ask me.)
It sounds like you're expanding the story, using more insect species. Interesting.
Perhaps you've got the rationale behind doing such a strange thing, I'm interested in what ideas you've come up with. I think knowing why would help begin to answer the question of the psychological ramifications of the new creatures. Mostly because, if the genetic science is advanced enough to "hybridize" humans with the species you list, why wouldn't the scientists simply give the hybrids the physical characteristics, and not the psychological changes? I mean . . . wouldn't the bug people be mostly subject to id desires (mating/eating/sleeping)?
Say more about the rationale behind the project. (Evil mad scientist? Creating hyper-alert soldiers? Simply an accident? << Unlikely.)
