Hosts in Abutilon:A. theophrasti (buttonweed)

A dead stem I examined in winter had had its lowermost portion hollowed out by an unknown insect when the stem was alive during the previous growing season. The tunneling presumably extended into the roots, but I did not observe this directly. The culprit was no longer present.
