Lagoa crispata (Packard, 1864) - Black-waved Flannel Moth



view caption
Taxonomy
Superfamily: Zygaenoidea Family: MegalopygidaeP3 Number: 660061.00 MONA Number: 4644.00
Comments: One of four members of this genus in North America, two of which occur in North Carolina. Variably placed in the genera Megalopyge and Lagoa, it is currently assigned to the latter.
Identification
Field Guide Descriptions: Covell (1984)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1923)Technical Description, Immature Stages: Wagner (2005)                                                                                 
Adult Markings: This is a heavy-bodied species with a furry head and thorax that is medium to pale yellow. The legs are also furry and pale yellow, with prominent black tips. The forewing is pale yellow with wavy "hairs" across the basal half that imparts a distinctive wrinkled or woolly appearance. The most obvious marks are discrete black waves running just above the costa, typically with several orange or brown waves beneath. These marks vary in intensity in the female and on worn individuals. Lagoa crispata is similar in size and shape to M. opercularis but the forewings are pale yellow rather than orange-brown as seen in the latter. In addition, M. opercularis tends to have more extensive black scaling on the tips of the legs.
Wingspan: 25-25 mm (Forbes, 1923)
Adult Structural Features: Males have pectinate antennae that 2/3 as long as the forewing, whereas those of male M. opercularis are only about 1/2 the length of the wing (Forbes, 1923). Forbes describes the forelegs of crispata as pale with black tips; in our specimens, the tarsi of all of the legs appears to be pale, with only the metatarsi black. In M. opercularis, in contrast, both the tarsi and metatarsi are blackish.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larvae are generalists and primarily feed on the leaves of hardwood trees and shrubs. The early instars have a sordid white body that is covered by thin, long, fluffy white hairs. In the older instars the body has a pelt of shorter, dense hairs that are soft, smooth and directed backwards. The body tapers to a wispy "tail" that is composed of setae that barely extend past the body, unlike the much more prominent "tail" of Megalopyge opercularis. The coat varies from orange to grayish and the hairs are sufficiently dense to conceal the body. The larvae are very similar to those of Lagoa crispata and best identified by either rearing or geographic range (Wagner, 2005). The larvae are capable of producing a painful sting or sometimes more serious reactions due to urticating hairs on the body (Wagner, 2005; Mullen and Zaspel, 2019).
Larvae ID Requirements: Identifiable only through rearing to adulthood.
Distribution in North Carolina
Distribution: Probably occurs statewide, from the Barrier Islands to the High Mountains

Habitats and Life History
Habitats: Our records come from essentially every habitat type in the state, including maritime forests and scrub; peatlands; Longleaf Pine savannas, flatwoods, and sandhills; bottomland forests; mesic to dry slopes in the Piedmont and Mountains, including northern hardwoods at our highest elevations.
Larval Host Plants: Polyphagous, feeding on a variety of shrubs and trees including Alder, apple, Birches, Blackberries, Oaks, Poplars, Cherries, Sassafras, Willows, and many others (Wagner, 2005). In North Carolina, we have observed the species feeding on beech and redbud. - View
Observation Methods: Readily attracted to lights. Adults have only reduced mouthparts and probably do not feed; consequently, they do not come to bait or flowers.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: G5 [S5]
State Protection: Has no legal protection, although permits are required to collect it in state parks and on other public lands.
Comments: This species occurs widely across the state, occupying a broad range of habitats, and utilizing a large set of host plants, including many that are common. Consequently, this species appears to be quite secure in North Carolina
