Datana integerrima Grote & Robinson, 1866 - Walnut Caterpillar Moth


Taxonomy
Superfamily: Noctuoidea Family: NotodontidaeSubfamily: PhalerinaeP3 Number: 930038.00 MONA Number: 7907.00
Comments: One of 16 species in this genus, all but one of which occurs in North America north of Mexico (Miller et al., 2018). Nine have been recorded in North Carolina.
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONATechnical Description, Adults: Forbes (1948); Miller et al. (2018)Technical Description, Immature Stages: Forbes (1948); Wagner (2005); Miller et al. (2018)                                                                                 
Adult Markings: One of five Datanas in our area with a smooth outer margin of the forewing. The head is yellowish but the collar, tegulae, and mesothorax are contrastingly dark, reddish-brown. The ground color of the forewing is reddish-brown and is rather evenly colored and not peppered with brown or silvery scales. The lines are bordered outwardly with pale yellow (Forbes, 1948). Datana contracta is similar in pattern but the ground color of the forewings is golden-yellow, strongly peppered with darker brown scales (Forbes, 1948; Miller et al., 2018).
Wingspan: 35-50 mm (Forbes, 1948)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Larvae are black and covered by long white setae. A white subspiracular stripe is present but the other pale stripes typically found in Datana larvae are present in young instars but often absent or only weakly developed in later instars (Wagner, 2005; Miller et al., 2018). Molting is synchronized and takes place in clusters on tree trunks.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.

Habitats and Life History
Habitats: Woodlands and parks and orchards containing Pecans (Wagner, 2005). Our records come from both xeric hardwoods, including maritime forests and inland sand ridges -- presumably in association with Mockernut or Sand Hickory -- and from mesic slopes and bottomlands, where Walnuts are common.
Larval Host Plants: Larvae feed on members of the Juglandaceae, including Walnut, Butternut, and Hickory (Wagner, 2005; Miller et al., 2018).
