An ootheca /oʊ.əˈθiːkə/ (pl. oothecae /oʊ.əˈθiːsiː/) is a type of egg mass made by any member of a variety of species (usually insects or mollusks).
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.
An ootheca usually contains many eggs surrounded by a foam of protein which may then harden into a tough casing for protection. Notable ootheca-making insects are the mantis and cockroach.[1]
It is formed by secretion of collateral glands, over 16 fertilised eggs are arranged in 2 rows of 8 each. They are found in genital pouch of female cockroach or mantis.
