See text Panorpa is a genus of scorpion-flies that is widely dispersed, especially in the Northern Hemisphere.

[4] The species P. vulgaris, has become a model insect for testing theories of sexual selection as its mating system has been noted to be similar to that of humans in some aspects.

The production of nuptial gifts during copulation in males (e.g. salivary secretion) and high nutritional condition in females are indicators of "good foraging genes", an indirect benefit that individuals look for in their partners.

These genetic benefits can increase fitness in offspring and improve their foraging ability.

[6] The life-cycle of Panorpa nuptialis and its habits, have become of interest in the field of forensic entomology.
