Explanation of Names
Gymnetis caseyi Antoine, 2001
Patronym for Thomas Casey (1857-1925), one of the most prolific workers of North American Coleoptera.
Ratcliffe determined 18 spp. within Gymnetis, but only G. caseyi reaches the U.S.
TX-LA, FL / Tamps & SLP, Mex. (1),(2),(Quinn, 2008)
mostly May-Sept (based on spmns in the TAMUIC) (3)
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. (4)
See Also
Gymnetina cretacea (LeConte) is frequently incorrectly listed on various websites as Gymnetis cretacea.
Gymnetina 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.
