Crambus laqueatellus
Clemens, 1860
Eastern Grass-veneer
Crambus laqueatellus, commonly known as the Eastern Grass-veneer, is a in the Crambidae. It was described by James Brackenridge Clemens in 1860. The species is widespread across eastern and central North America, with active from spring through late summer. Larvae are grass-feeders, making this species a typical member of the grass-veneer group within Crambus.

Distribution
Eastern and central North America: recorded from Ontario and Maine south to South Carolina, west to Texas, and north to North Dakota. Additional records from Vermont confirm presence in New England.
Seasonality
are on wing from April to September, with peak activity likely varying by latitude. The extended period suggests multiple or continuous across the growing season.
Diet
Larvae feed on grasses (Poaceae). Specific grass have not been documented in the provided sources.
Life Cycle
Complete with , larval, pupal, and stages. Larvae are grass-feeders; likely occurs in soil or within grass thatch. Detailed timing is not documented.
Behavior
are and attracted to light. Larvae are concealed feeders within grass stems or thatch, typical of crambine grass-veneer moths.
Ecological Role
Larvae function as primary consumers in grassland , converting plant to animal tissue. They serve as prey for various including birds, , and other insects.
