Well now, that is a sticky one: Counting species, probably not, but if
you are counting individuals, the white-lined sphinx and others that can
be very common could throw the proportions of your count the other way
by several orders of magnitude. One spring day, I was in Box Canyon
(~160 miles east of Los Angeles in the Coachella Valley area [Colorado
Desert]) and saw some 30 white-lined sphinxes (Hyles lineata) nectaring
at Chilopsis linearis (mimbre) between 1045h and 1115h. So I am told,
this is not all that unusual for this species.
