Courtesy: Eduard JendekEgs are laid by a long mebraneous telescoping ovipositor allowing precise oviposition deep into bark crevices
Courtesy: Eduard JendekLarva of all Agrilus species is distinctive by abdominal apical pair of serrate styles
Courtesy: Eduard JendekOviposition occurs in the later part of warm, sunny days. Females lay egs in the obscure places in the bark.

Courtesy: Eduard JendekThe spined soldier bug (Podisus maculiventris) is a generalist predator with a broad host range. This is the first proof it attacks also EAB
Courtesy: Eduard JendekAsh borer moth (Podosesia syringae) loves weakened ashes. Its presence may indicate A. planipennis infestation
Courtesy: Eduard JendekTo reach sexual maturity, both sexes feed on the ash foliage. This type of leaf damage is defined as "margin feeding". Feeding is often accompanied by characteristic droppings
