It is very likely also found in < ahref=SphGuyana.htm>Guyana and Suriname.
Extremely similar to Isognathus excelsior but immediately distinguishable by the
brown underside to the abdomen (pure white with paired black spots in Isognathus excelsior).
Proposed as the new replacement name for Isognathus rimosa amazonica, Clark.

Excelsior also seems to have a much greater suffusion of white scales in the outer and upper regions of the forewing, and the black patches in the median area seem much darker in occidentalis than in excelsior.
Larvae have long tails; colouration suggests they are unpalatable to birds.
The pupae are also quite colourful, and, I suspect, are very lively. Moths generally emerge within 8-24 days of pupation.
