Bombyx hybrid Bombyx hybrid The "Bombyx" hybrid is a hybrid between a female "Bombyx mori" moth and a male "Bombyx mandarina" moth. They produce silkworm larvae like all species of "Bombyx". The larvae look a lot like the other variations. They are brown in the first half and gray at the bottom half, but they get larger black spots than other variations. Generally, they look like a normal "Bombyx" moth, but a bit darker. Hybrids are not used for silk, but are used for research. "Bombyx mori" females are much more likely to mate with a male "Bombyx mandarina", but both species
Crustacean larva Crustacean larva Crustaceans may pass through a number of larval and immature stages between hatching from their eggs and reaching their adult form. Each of the stages is separated by a moult, in which the hard exoskeleton is shed to allow the animal to grow. The larvae of crustaceans often bear little resemblance to the adult, and there are still cases where it is not known what larvae will grow into what adults. This is especially true of crustaceans which live as benthic adults (on the sea bed), more so than where the larvae are planktonic and therefore more easily
