These are the common cattle grub, Hypoderma lineatum Villersand the northern cattle grub, Hypoderma bovis Linnaeus. Cattle grub larvae are true maggots, with retractable heads and no sclerotization or legs.

The first of these is an ability to kill migrating larvae, but unlike systemics, it is also highly efficacious at extremely low dosages against second- and third-instar larvae in warbles.
