Abstract
Lepidopterans play an integral role in high altitude Rocky Mountain ecosystems as larval herbivores and, more importantly, as pollinating adults. Lepidopterans also constitute a major food source for many other invertebrates and vertebrates in Rocky Mountain food chains. However, very little is known of the important lepidopteran aspect of ecology within Wyoming ecosystems, and virtually nothing of scientific value has been published on the lepidopterans of the National Parks in Wyoming.
