Agrilus vittaticollis
Hawthorn Root Borer
Agrilus vittaticollis, commonly known as the hawthorn root borer, is a metallic wood-boring beetle in the family Buprestidae. It is one of several larger, more conspicuous Agrilus species characterized by a red pronotum and black elytra. The species develops in living rather than dead host plants, specifically in serviceberry (Amelanchier). It is found in North America but is not commonly encountered compared to many other Agrilus species.
Dicerca pugionata
witch-hazel borer, ninebark borer
A striking jewel beetle in the family Buprestidae, measuring 11–14 mm in length. Unlike most Dicerca species that breed in dead wood, D. pugionata larvae mine living stems of woody shrubs. The species occurs sporadically across eastern North America but reaches locally abundant populations in Missouri glades where host plants grow under stressed conditions.
