Insect Flight: Origins & Aerodynamics

There are two competing hypotheses for the origin of flight in insects. One is that the first terrestrial hexapods had extensions coming out of their thorax that helped them glide between the tall vegetation of the time; an evolutionary path from simple paranota (unmoveable stubs) to an insect wing is …

Parasites Affecting Insect Behaviour

Parasites need to have adaptations for colonisation, defeating immune systems and transmission. Often, parasitism involves very complex interactions between not-so-closely-related organisms. For example, the jungle-dwelling turtle ant above is infected by nematodes that gather and mate in the gaster (hind part of the ant). They deteriorate the cuticle of the …
