Zale strigimacula
Little Lined Zale
Zale strigimacula, commonly known as the Little Lined Zale, is a of in the Erebidae. It belongs to the Zale, a group of owlet moths whose caterpillars feed on various woody plants. The species is part of the diverse North American noctuid fauna and is known to be a for including Ammophila nigricans. The genus Zale is taxonomically complex with many similar species, making field identification challenging.

Identification
The Zale contains numerous similar that are difficult to distinguish without close examination. Species in this genus typically have cryptic coloration in shades of brown, gray, or black, often with fine lines or patterns on the forewings. The specific epithet "strigimacula" refers to streaked or lined markings. Accurate identification usually requires examination of genitalia or reference to regional faunal works. The species may be confused with other Zale species such as Zale horrida or Zale galbanata, which share similar size and wing patterns.

Distribution
The occurs in North America, with records from the eastern and central United States. The Zale is broadly distributed across North America with highest diversity in the eastern deciduous forest biome.
Seasonality
are active during the warmer months, with periods typical of temperate noctuid . Most Zale have one or two per year, with adults flying from late spring through early autumn depending on latitude.
Diet
Larvae feed on woody plants, particularly in the Pinaceae including pines. The caterpillars are feeders on needles.
Host Associations

Life Cycle
Complete with , larva, pupa, and stages. Larvae are solitary feeders. occurs in soil or leaf litter.
Behavior
are and attracted to light. Larvae feed at night and rest during daylight hours concealed in foliage or on bark.
Ecological Role
Larval stage functions as a primary consumer of conifer foliage. The serves as prey for including Ammophila nigricans, which provisions its nests with Zale caterpillars. This parasitoid relationship contributes to and nutrient cycling in forest .
Human Relevance
