Solution(By Examveda Team)

The mustard saw fly (Athalia proxima) lays eggs near Leaf margin.
The mustard sawfly breeds from October to March and undergoes pupal diapause during summer. The adults emerge from these cocoons early in October.
They live for 2 - 8 days and lay 30 - 35 eggs singly, in slits made with saw-like ovipositors along the underside of the leaf margins. Egg period is 4 - 8 days and the larvae feed exposed in groups of 3 - 6 on the leaves during morning and evening.
