Cornulactica varicornis (Jacoby)
Orig. Comb: Lactica varicornis Jacoby 1881
1 sp. n. of Mex.
southmost TX (Cameron Co.) to New Orleans, LA / Mex. to C. Amer. (Jacoby 1881),(BG data),(1), plus one record from Caatinga, Brazil (da Silva Guedes, et al. 2019)
broadly along the Gulf coastal plains (Jacoby 1881),(BG data),(1)
US records from May, July, Oct. (BG data)(1)
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
all three US records came to lights (BG data)(1)
known from three US records as of Jan. 2020:
Brownsville, Cameron Co., Texas - Oct. 2002 (BG data) - (not included in Riley et al. (2003)(3))
618 Robert St, New Orleans, Louisiana - May 2019 (1)
Allen Acres, Pitkin, Vernon Parish, Louisiana - July 2019 (BG data)
