Black Vine Weevil Larva	Black Vine Weevil Adult
	Black vine weevil is not as abundant in mint as the strawberry root weevil. Larvae are c-shaped, cream-colored with a brown head capsule.  Larvae feed on roots and rhizomes.  Larvae are about 8 mm long when mature.  Adults are black or dark brown and about 8 to 10 mm long.  Adults are marked with yellow patches on the back. Adults feed at night and notch the leaf margins.   Pupae are cream- colored and are found about 10 to 15 cm deep.  Adults emerge in late April, May and early June and begin laying eggs about 2 weeks later.   Larvae feed from September through April of the following year and cause the most damage on roots from late March to mid-May.
