The egg chorion of the dog louse Heterodoxus spiniger bears pentagonal / rectangular scutes (scale like sculpturing) arranged obliquely. The opercular disc of the egg bears tall cup shaped micropyles which unite to give ridge like appearance. The centre of the disc bears short thick rod like polar thread.

TLDR
It was found that the markings present on the egg cases of avian lice could be used to differentiate the genera and species of phthirapteran species infesting different avian hosts.
