Genus Callibaetis
Explanation of Names
Callibaetis Eaton 1881
Numbers
12 spp. in our area(1), 30 total(2)
Identification
Female imagoes usually with intensely colored leading edge of the forewing, males may have this coloration less pronounced or lacking; subimagoes typically have dull grey, brown, or tan wings with a network of pale veins (based on Lloyd Gonzales's comment)
Range
New World, more diverse in the Neotropics(2)
Remarks
Following mating, female imagoes of genera Callibaetis and Cloeon seek a safe place to remain stationary for five days or so, until their eggs have matured; then the female flies off to land on the water, and deposit her load of eggs, which immediately start hatching. This behavior is unique to Callibaetis & Cloeon: in all other mayflies the eggs require up to two weeks following oviposition to begin hatching. (Roger Rohrbeck's comment)
