According to the researchers, the mouth of the larvae Blepharotes splendidissimus “resembles a Swiss army knife.” They have sharp lower jaw hooklike form, with which they dig into the body of other insects. Pictures of tiny larvae have been obtained by electron microscopy. They are published in Austral Entomology.
Biting the victim, the larva injects it with poisonous saliva through a tube in the jaws and then the same “tool” sucks out the insides of the insect.
The study’s authors argue that flies are killer and their larvae can be very useful to farmers in combating the pests.
