Catocala amica lineella, the Little Lined underwing, Hodges# 8878.1, (wingspan: 35-40mm) flies from Ontario and Quebec south to Florida west to Texas and north to Ohio.

In some classifications lineella is given full species status. Moths come in to lights and to bait.

Like C. amica, this species does not have a marginal black band on the hindwing. The forewing subreniform spot is pale and boldy outlined with black. There is a similar light brownish-gray patch in the upper half of the median area near the pm line, and just between the subreniform spot and the antemedian line there is a similarly coloured light patch paralleling the am lne.

The reniform spot is dark, less distinct and in a generally darker area.

The form "curvifascia" has a diffuse black-brown arc from the mid costa region toward the mid outer margin.

Catocala amica lineella are usually on the wing from June until September.

Tim Dyson sends this nice ventral shot from Peterborough, Ontario, July 25, 2006, of a male feeding on fresh banana-beer mush. It took some time to entice the moth to land on and feed from the offering on the stick.

The Catocala amica lineella caterpillar shows a preference for oak species and probably limits itself to members of the Quercus genus.


Adults eclose from pupae at soil surface.


Catocala amica lineella females emit an airbourne pheromone and males use their antennae to track the scent plume.


Eggs are deposited on tree bark in the fall and hatch the following spring.
