Agrilus cyanescens
Agrilus cyanescens is a metallic wood-boring beetle in the family Buprestidae. The species is native to Europe and Northern Asia (excluding China) and has been introduced to North America, where it is now considered invasive. It has been newly recorded in Connecticut and other eastern states. Two subspecies are recognized: A. c. cyanescens and A. c. johanidesi.
Neoclytus caprea
Banded Ash Borer
Neoclytus caprea, commonly called the banded ash borer, is a North American longhorn beetle in the family Cerambycidae. Adults display striking yellow and black (females) or white and black (males) banded coloration that mimics wasps. The species develops in the sapwood of ash, hickory, elm, and oak trees, completing one generation per year. Unlike the invasive emerald ash borer, this native species primarily colonizes stressed, dying, or recently dead wood rather than healthy trees.
Neoclytus conjunctus
Western Ash Borer
Neoclytus conjunctus is a species of longhorned beetle in the family Cerambycidae, described by LeConte in 1857. It is commonly known as the Western Ash Borer. The species belongs to the Clytini tribe, a group known for wasp-mimicking appearance and rapid movement. Like other Neoclytus species, it is associated with woody hosts and is distributed in western North America.
