Guenée, 1852

oblique zale

Zale obliqua, the oblique zale, is a noctuid first described by Achille Guenée in 1852. The is associated with pine in eastern North America, with larvae feeding on pitch pine in northern and likely other pine species in southern populations. exhibit regional variation in timing, with activity beginning in late March in southeastern North Carolina and early summer in more northern latitudes.

Appearance

Medium-sized with wingspan of 36–40 mm. Forewing pattern exhibits less contrast than related Zale and lacks the bluish-gray band present in some . Overall coloration relatively subdued.

Habitat

Barrens and pine woodlands. Associated with sandy, open dominated by pine .

Distribution

Eastern United States from Ohio to southern Maine, south to northern Florida, west to Mississippi and Texas.

Seasonality

active late March in southeastern North Carolina; early summer (approximately May–June) from New Jersey northward. One per year from New Jersey north; two generations from eastern Maryland to northeastern North Carolina southward.

Diet

Larvae feed on pitch pine (Pinus rigida) in northern range; likely loblolly pine (P. taeda), pond pine (P. serotina), and longleaf pine (P. palustris) in southern range.

Life Cycle

Holometabolous development with one annually in northern portion of range and two generations in southern portion. Specific details of , larval, and pupal stages not documented in available sources.

Ecological Role

herbivore of pine ; contributes to nutrient cycling in pine barren and woodland . Larval feeding may influence pine foliage dynamics, though impact is likely minor given natural levels.
