Explanation of Names
Epstein & Becker (1993) (1) transferred Monoleuca obliqua Edwards, 1886 to Euclea and synonymized Euclea dolliana Dyar, 1905, Euclea flava Barnes & McDunnough, 1910 and Monoleuca spadicis Grossbeck, 1906 with this species.
Forewing length 11-13 mm. (2)
Larva - late instars are red, purple, yellow, blue and green beauties with many spines.
Southern Arizona and New Mexico. (2) Described from a specimen collected in Indian River, Florida.
Larval hosts include New Mexican locust (Robinia neomexicana), sandbar willow (Salix exigua) and manzanita. (3), (2)
"Euclea obliqua is correct name
This species is not in the genus Monoleuca. Superficially the adult stage look alike and share some venation characters (fused R3 + R4), but this is shared with Adoneta species as well. The genitalia of both sexes more closely match Euclea, which is why I placed there when I synonymized Euclea dolliana with this species. The type of obliqua was mislabeled being collected in Florida by Henry Edwards. [see Epstein, M. E. & V. O. Becker. 1994. Combinations and Synonymies in New World Limacodidae, Megalopygidae, Lasiocampidae and Arctiidae (Lepidoptera). Revista brasileira de Zoologia. 10:289-319. (1993); Becker, V. O. & M. E. Epstein. 1995. Limacodidae. in J. B. Heppner (ed.), The Atlas of Neotropical Lepidoptera. Checklist: Part II. 3:128-133.
Monoleuca semifascia and Monoleuca rectifascia are the only two species in this genus. Both share uniquely derived features of the male and female genitalia, which include a dense scale pack that covers the eggs, the only known example in the New World (this has occurred independely in Australia). [see Epstein, M.E. 1996. A new name and generic placement for the misidentified type species of Epiclea Dyar, 1905 (Lepidopetera, Limacodidae). Proc. Entomol. Soc. Wash. 98:812-817." -Marc Epstein (2014) (See original comment here)
