Found from Costa Rica south to Colombia and east
to the Guianas. Generally not common, and quite rare in Costa Rica the
southern parts of the range. Many feel that ascolius should
be classified as a subspecies of zagreus,
and the zagreus subspecies, motilones, is felt by some to
be an intergrade form, though I feel it belongs with zagreus and ascolius
is sufficiently distinct to be classified as a full species. The Northernmost
population falls under the subspecific name zalates; populations
from W Colombia represents subspecies daguanibus, and the variety
from SW Colombia and W Ecuador is the (rather rare) rosenbergi.
