gall

oviposition on the shoot tip, between the youngest leaves or in the inflorescence. During about a month the larve performs as a stem borer, tunnelling its way down to the underground base of the stem. Here the stem swells to an onion-like gall of about 1.5 cm high. The stem above the gall dies off. The larva lives for another 4-6 weeks in the gall, ultimately pupating there.
