竹广肩小蜂和竹长尾小蜂是竹林瘿小蜂类的优势种。研究表明广肩小蜂１ａ一代，以蛹在虫瘿内越冬：成虫２月中旬至４月中旬羽化，３月下旬至４月下旬出瘿，产卵于萌动小枝芽基部的节间内并形成虫瘿，在虫瘿内完成卵、幼虫和蛹的发育；幼虫发生期４月上旬～９月中旬，５龄，以虫瘿内壁组织为食。长尾小蜂１ａ一代，以幼虫在虫瘿内越冬；成虫于４月中旬至５月上旬羽化、出瘿，产卵于已被广肩小蜂产卵的芽中；幼虫孵化后占据广肩小蜂的虫瘿，幼龄时可食广肩小蜂幼虫虫体，但以植食为主；幼虫５龄，发生期５月上旬至次年３月下旬，１１月后渐渐老熟、越冬。
Bamboo wide-shouldered wasp and bamboo long-tailed wasp is the dominant species of bamboo beetle. Studies have shown that the broad-shoulders wasps 1a generation, the pupal wintering within the insects: adult mid February to mid April emerge, late March to late April out of the ridge, the sprout in the sprout buds bud base of the internode and the formation of Bugs, complete eggs, larvae and pupae development within the bugs; larvae occurred in early April to mid September, 5th instar, feeding on the inner wall of the buzzard. Larvae larvae larvae in the winter over the winter; insects in mid-April to early May emergence, emergence, spawning in the bud has been broad shoulders wasp spawning; larvae occupy wide shoulders after hatching The larvae of 5-year-old larvae, occurring from early May to the end of March next year, mature gradually after November and overwinter .
