Explanation of Names
Agrilus planipennis Fairmaire 1888
Size
adult 7.5-14 mm (males smaller than females); larva up to 32 mm
Identification
Adult: elytra bright metallic green; pronotum golden-green; ventral surface lighter yellowish-green (with fine hairs in males, lacking in females); body narrow and elongate; head flat; eyes kidney-shaped, black; dorsal surface of abdomen metallic purplish-red, visible when wings are spread
generally larger and brighter green than native NA spp.
Larva: body white to cream-colored, dorso-ventrally flattened; head brown, mostly retracted into prothorax; abdomen 10-segmented with pair of brown pincer-like appendages on last segment; segments 5-8 widen posteriorly, giving the abdomen a serrated appearance when viewed from above
Range
native to E. Asia, accidentally introduced to NA, established around the Great Lakes (see distribution map) and has spread as far as IA, KS, TN, & MA
state by state data here
Season
adults in spring and summer; larvae in summer and fall
Food
hosts: Fraxinus spp.; larvae feed on inner bark of ash trees, disrupting the flow of water and nutrients, and killing infested trees within 1-4 years; adults feed on ash leaves
Life Cycle
one generation per year; overwinters as larva in outer sapwood/bark; pupate in April-May; adults emerge in late spring through D-shaped exit holes and lay eggs on host tree; larvae chew through outer bark and bore S-shaped tunnels in inner bark until late fall, then stop feeding
Remarks
Accidentally introduced with imported packaging/crating wood, probably in the late 1990s; first reported in se. MI and sw. ON in 2002.
A highly destructive pest and a major economic & environmental threat to urban and forested areas of eastern NA
Wasp (Cerceris fumipennis) preys on this species and is used to detect the presence of EAB (more here)
