Mantis ootheca

An ootheca

egg capsule made by any member of a variety of species including mollusks (such as Turbinella laevigata), mantises, and cockroaches.[1][2][3]

Etymology

The word is a Latinized combination of oo-, meaning "egg", from the Greek word ōon (cf. Latin

ovum), and theca, meaning a "cover" or "container", from the Greek theke. Ootheke is Greek for ovary
.

Structure

Oothecae are made up of structural

Coleoptera) and Korinninae (Phasmatodea).[6]

Functions

The ootheca protects the eggs from

parasitoids, predators, and weather; the ootheca maintains a stable water balance through variation in its surface, as it is porous in dry climates to protect against desiccation, and smooth in wet climates to protect against oversaturation. Its composition and appearance vary depending on species and environment.[7][8][3]
