The Garden Mantis (Orthodera ministralis) is a species of praying mantis found in Australia. It is part of the family Mantidae, that includes almost 75% of all praying mantid species in Australia.

Many species of praying mantids including the garden mantis have distinctive egg cases or ‘ootheca’, a word to describe the egg case of cockroaches, mantises, and related insects. The Garden Mantid ootheca is about 2 cm in length and is hard and woody. It is often seen attached to vegetation, fences, buildings and fly screens.

The word is a Latinized combination of oo-, meaning “egg”, from the Greek word ōon, and theca, meaning a “cover” or “container”, from the Greek theke. Ootheke is Greek for ovary.

It is carnivorous and feeds on small insects including aphids.
