Distribution Data for Megalopyge lacyi
Large Map & Chart Report Errors About Maps
Distribution: Possibly central TX to NM. Range is uncertain. Based on larval characteristics, specimens identified as lacyi from southeastern US may represent a regional color variation of crispata (Sancio et al., 2024) or possibly a novel species (Sancio in iNaturalist, pers. comm., 18 Sept., 2022)
Type locality: Kerrville, TX.
Field Marks:
Records from Florida may refer to Megalopyge crispata (Packard, 1864) and/or a cryptic, possibly undescribed, species.
Similar Species:
  • Megalopyge crispata (Packard, 1864)
  • Megalopyge immaculata (Cassino, 1928) may be conspecific with lacyi. (Sancio et al., 2024)
  • Pinned specimens of related species. (Hint: select View by Region on the related species page.)
Synonymy: Lagoa lacyi Barnes & McDunnough, 1910
Lagoa laceyi Barnes & McDunnough, 1917
Taxonomic Notes: Megalopyge lacyi was listed in the genus Lagoa in Hodges et al. (1983) (Checklist). This genus was treated as a synonym of Megalopyge by Neumoegen & Dyar (1894). This synonymy was reversed and then reapplied several times since. Becker (1995) reinstated the synonymy.
