Explanation of Names
From Latin vern meaning "the spring'
Powell & Opler (2009) reported three described species of the genus Paleacrita in North America. (1)
Male forewing length 11-18 mm., females wingless. (1)
Nova Scotia into Saskatchewan, Maine to Tennessee and North Carolina in the mountains. It is found in the central United States from Michigan to North Dakota, south to Mississippi, Louisiana, and eastern Texas. It is known from Colorado, and there is one record from Siskiyou County, California
Adults fly from February to late May. (1)
Larval hosts are a wide variety of broadleaf trees and shrubs, to include maple, elm, birch and plum (1)
Life Cycle
wingless females lay batches up to 250 eggs under loose bark or in crevices. Early instar larvae disperse by ballooning on silken threads. Full grown larvae drop from the host and pupate in the soil without making a silken cocoon. Winter is passed as pupa (1)
