Synonyms and other taxonomic changes

Cornulactica varicornis (Jacoby)

Orig. Comb: Lactica varicornis Jacoby 1881

Numbers

1 sp. n. of Mex.

Range

s. MS to Houston, southmost TX to C. Amer. (Belize) (Jacoby 1881)(BG data)(1), plus one record from Caatinga, Brazil (da Silva Guedes, et al. 2019)

Habitat

broadly along the Gulf coastal plains (Jacoby 1881)(BG data)(1)

Season

April-Oct in US (BG data)(1)

Food

genus not reported in Clark et al. (2004) (2), but USDA (1985) reports an intercept of this species from Mexico on Musa sp. (Musaceae), a genus that includes bananas and plantains.

Cornulactica is related to “Monomacra s. lato” that will use Passiflora spp. and some on Bumelia, but those seem unlikely [hosts] to me. (E.G. Riley, pers. comm. to MAQ, 2020)

Life Cycle

comes to UV lights (BG data)(1)

Remarks

Apparently introduced into s. Louisiana ca. 2019 and recently (2022) spread to the Upper Coast of Texas and to s. Mississippi. (BG data)(1)
