I too have read something like this in the VPI book, the only problem with the creatures they were talking about was they were very hard to keep alive for any amount of time, and it took several "rounds" if you will. I don't know how those bugs did with the eggs, because it would seem to me that the bugs would only eat the moving adults, and not the eggs after they had been laid. Leaving the door open for a reinfestation.
But, I think it's something worth mentioning like you hadI have no idea if they were the same insect or not.
