A study was conducted on the changes of glycerol, hemolymph proteins, glucogen and fat content of diapause and non-diapause pupae of Helicoverpa assulta.
In the present study, observations were made to determine if the yolk protein, vitellin, was released from the ovaries into the hemolymph without degradation during oosorption.
The wasp snaps the cockroach's antennae in half, uses the broken pieces as straws to feed off its blood-like hemolymph, then leads it into a subterranean lair.
The carminic acid molecules are stored as clumps in her hemolymph – the insect equivalent of our blood – and ward off some would-be predators, like ants, and harmful microbes.
