Few larvae were obtained in laboratory from the eggs and were reared to pupa about one month, but there were not obtained any new adults 4. The larvae LI hatched in Mid September, body is fusiform with wider head and thorax, length of first instar on the 1 st to 3 rd days is 4.5-4.9 mm.; width of head capsule is 0.6-0.7 mm. 5 This is L2 instar. The length of second instar on the 8-9 days is 9.2-9.6 mm, width of head capsule 0.8—0.9 mm. 6. Like L2, L3 has a bight voracity. The head and thorax are dark brown, abdominal tergites with gray plates. The length of L3 on 14—15 ds is 12—13 mm. L3 before pupation is 16.5-17.0 mm. All larval stage duration are 24 to 27 ds. This species is frequent in the rich soil on the borders of standing water.
