Highly variable in color, even within a single species. Petiolate abdomen - the first segment of the metasoma is distinctly stalked, very narrow at the base and flares out to be at least 2.5 times wider at the end. Unlike most other braconids, they possess a distinct four-sided (rhomboid or square) second submarginal cell in their forewings. The rear of the thorax features distinct longitudinal furrows, and each abdominal segment typically has a single transverse row of stiff hairs (setae) near its rear margin. They possess a pair of small pit-like depressions (dorsopes) on the upper side of the first abdominal tergite. Females always have a prominent ovipositor protruding from the end of the abdomen. 

Unless identified by a recognised expert, a photo is required and the specimen should be examined with a microscope. In the comments box, state the key or ID method used and describe the size and identifying characters.

Most species of Meteorus are koinobiont endoparasitoids of lepidopteran larvae, but some species attack larval Coleoptera.
