The synthesis capability of some amino acids is lost during the insect evolution, and hymenopteran parasitoids can make up for these deficiencies by altering free amino acid concentrations in host.

The propensity to endogenize and domesticate dsDNA viruses depends on lifestyle in Hymenoptera.

A fatty acyl reductase gene family expansion in the Hymenoptera crown group led to recruitment of novel pheromone-biosynthetic enzymes and is linked to evolution of pheromone marking behavior.

To protect their food and themselves against detrimental mould fungi, the eggs of a wasp species synthesize and emit remarkable amounts of gaseous nitrogen oxides that are highly effective antimicrobials.

How biologically relevant chemical information can be genetically maintained and conveyed in complex sex pheromonal profiles.

An insect-like mushroom body in one group of crustaceans, the mantis shrimps (Stomatopoda), suggests either an ancient origin of this center and its reduction and loss in other crustaceans, or an extraordinary example of convergent evolution with the insect mushroom body.

Variation in the rate of alternative splicing across animals are mainly driven by differences in the rate of splicing errors.
