Explanation of Names
Junonia neildi Brévignon, 2004, formerly a subspecies of Junonia genoveva (Cramer, 1780), is elevated to full species status in Brévignon (2009). The subspecies J. n. varia Grishin, 2020 replaces teh names litoralis and genoveva in Texas. The species genoveva and litoralis are now treated as extralimital north of Mexico in Cong et al. (2020).
50-55mm wingspan
Dorsal, brown with eyespots on both FW and HW. Compare with Common Buckeye and Tropical Buckeye.
Ventral, brownish with indistinct markings. Compare with Common Buckeye, and Tropical Buckeye.
USA: Florida (neildi); coastal south Texas (varia).
Type locality (J. n. neildi): Guadeloupe.
Type locality (J. n. varia): Goose Island State Park, Aransas Co., TX.
Black mangrove swamps and adjacent clearings.
All year, with multiple broods.
Black Mangrove (Avicennia germinans) - Acanthaceae
Classification of taxa in the genus Junonia occurring in North America was revised in Cong et al. (2020) (1). This revision is followed here at BugGuide. It is unclear how universally those findings have been accepted. The notes from prior to this publication are preserved below:
Many sources will have Mangrove Buckeye (J. genoveva), and Tropical Buckeye (J.evarete) reversed. See comments regarding this confusion under the Info section for the genus Junonia.
note that the names Junonia evarete and Junonia genoveva are reversed in some of the references cited (and the distributional data is confused at the Nearctica web site); so, look at the common name (Mangrove Buckeye) to find this one. However, the information given is still helpful.
