Synonyms and other taxonomic changes
Gymnetis flavomarginata
Gymnetis sallei
G. sallei and G. flavomarginatea correctly apply to species that occur from southern Mexico south into South America
Numbers
Ratcliffe determined 18 spp. within Gymnetis, but only G. caseyi reaches the U.S.
Range
Gymnetis caseyi occurs in Texas, Louisiana, Florida, Tamaulipas & San Luis PotosÃ.
Season
There are 77 G. caseyi specimens in Texas A&M collection collected between March and December, most from May to September.
Food
Adults readily come to bait. However, little is known about the habits of the larvae. Ritcher (1966) reported three third-stage larvae collected December 31, 1919, at Blue Mott, Victoria Co., TX in rotten moss in a hollow anacua (Ehretia anacua) tree.
See Also
Gymnetina cretacea (LeConte) is frequently incorrectly listed on various websites as Gymnetis cretacea.
G. cretacea occurs in Arizona and New Mexico. This species is similarly patterned, but black and white vs. yellow.
There may be a second, similar species of Gymnetina occurring in AZ-NM.
