Members of the family Buprestidae are called jewel beetles or metallic wood-boring beetles. There are over 15,000 species known worldwide (classified in over 750 genera). Larvae typically live in dead or dying branches of trees (as well as fallen logs). The larvae typically have a flattened appearance. The introduced Emerald Ash Borer (Agrilus planipennis Fairmaire, 1888) is a member of this family.
