Most of the beetle's life is spent as a larva, with only 30–45 days spent as an imago. Adults feed on leaf material above ground, using pheromones to attract other beetles and overwhelm plants, skeletonizing leaves from the top of the plant downward. The aggregation of beetles will alternate daily between mating, feeding, and ovipositing. An ...

Asian long-horned beetle larvae do not pupate before they reach a critical weight, so additional larval instars can occur. [ 2 ] Pupation usually occurs in spring at the end of the larval tunnel in the sapwood , eclosion occurs 12–50 days later, and adults will chew out of the tree approximately one week after eclosion.

[ 2 ] The number and pattern of spots varies greatly between individuals, with some beetles possessing almost no spots, while others have many.
[39] [49] [50] His work showed that diverse bugs, beetles, and flies attack and consume beetle larvae, including several species with defensive secretions similar to P. vitellinae. Some ladybird beetles, including Calvia quindecimguttata and Oenopia conglobata consume leaf beetle larvae, while other aphid specializing ladybirds do not consume them.
