Etymology: An ootheca is the protective case that certain insects, such as mantises and cockroaches, wrap around their eggs. The word is a modern scientific coinage, built from two Greek-derived pieces: "oo-", from Greek "ōion" meaning egg, and "theca", a sheath or container. Its ancestry runs back through Latin "theca" to Greek "thēkē", from the same root as "tithēmi", meaning "to place". Put together, the parts describe exactly what the object is: an egg-container. Naturalists formed the term from classical building blocks, so no ancient Greek writer ever used "ootheca" for an insect's egg case, even though the Greek elements it draws on are very old. The pattern is the same as in other scientific names that combine "oo-" with a container word, where the first element is joined to the second to name a specific anatomical or biological structure.
