Nevada ony has six Sphingidae species that have recognized breeding populations throughout (T) the state. Many species
have more limited breeding areas, such as Manduca sexta whose larvae have only been encountered in the
southeastern one-sixth (SE 1/6) of the state. Hemaris diffinis larvae have been observed in the extreme northwestern (XNW)
parts of the state and in the extreme southeastern (XSE) parts of Nevada, while Hemaris senta has breeding populations in
all but (ab) the areas inhabited by H. diffinis. James P. Tuttle recognizes that H. diffinis and H. senta may represent
forms of the same species, or that there may be several different species involved in that group.
There are some species listed as strays, indicating that adult moths are sometimes taken in Nevada, but there
do not appear to be any overwintering or breeding populations.
