locust bean weevil - Amblycerus robiniae

locust bean weevil - Amblycerus robiniae
Nashua, Hillsborough County, New Hampshire, USA
March 17, 2019
Emerged from a locust pod kept in the warm house all winter. Interesting behavior; it remained curled up and unmoving for the majority of the day, moving around somewhat at night. Kicked its powerful back legs when touched, and used the back legs to clean elytra. None others have emerged from the pod. Difficult to determine what the adult feeds on; when offered apple it would would sit and walk around on it, but I couldn't tell if any was eaten. It wouldn't touch any other foods given. Also unsure of adult life span; originally found possibly up to a week after it emerged, kept presumably without feeding for a week, then it escaped and was found again two weeks later after also presumably having no source of food. It was then kept for another week or so with pieces of apple and then released. As it was not very active, perhaps energy needs were low.
