Mint Root Borer Pupa in Hybernaculum	Mint Root Borer Adult
	Larvae are cream-colored and about 15 mm long.  Adults are fawn to chocolate-brown, marked with darker lines.  Adults closely resemble false celery leaftier adults.  Eggs are nearly transparent to white, oval and flattened. Mint root borer overwinters as a prepupa in the soil. Pupation occurs in April and early May and adults emerge from June to early August. Eggs are deposited on the upper sides of leaves.  Larvae feed on leaves at first, then drop to the soil surface and enter rhizomes. Larvae feed for 70 to 80 days during August, September and early October.  There is one generation each year.
