Explanation of Names
TARDA: from the Latin "tardus" (slow), and the origin of the common name The Slowpoke. Wagner et al. notes that the aptly-named caterpillar is lethargic and will feign death when disturbed. (2)
The only species in the genus listed for America, north of Mexico. (1)
Wingspan 23-35 mm. (3); 14 to 15 mm long.
Larva to 3 cm. (2)
Adult - forewing dark grayish-brown; lines darker but usually inconspicuous; ST line wavy with pale tan to yellowish edging; spots inconspicuous, blackish; group of 4 pale dots around perimeter of reniform spot is diagnostic but not always present. (3); sometimes pale dots reduced to 1 or none.
Heppner (2003) listed the range as New Hampshire to Florida, Missouri to Texas. (4) , (5), (6), (7); Ontario
Very common in oak woodlands. (2)
Adults fly from April to September. BugGuide records indicate two distinct flights throughout the entire range, late-March through May and late-August through September. (3)
Larvae feed on dead oak leaves. (2), (3), (8)
Life Cycle
At rest on a dead leaf the larva presents a false head look with a swollen rearward segment and spots. When threatened the larva may raise rear abdominal segments and release anal prolegs to complete the deception. Lab reared caterpillars sometimes cannibalistic. (2)
