Initially this guide displays common species likely to be flitting right now. Use the selectors below to view by color, include rare species, or search by name.
Over 100 species of butterflies and skippers have been identified in the Los Alamos area, and over 150 in the Jemez Mountains. This guide mainly includes the common species, but even some of these are difficult to tell apart. For example, we have 4 species of fritillaries with very subtle differences.
In addition, there are an equally large number of moths in the area. However, most moths are active at night they are not as readily observed. Therefore, this guide primarily focuses on the moths that are more obvious due to their size or the fact that they are active during the day. The easiest way to tell a moth from a butterfly is to look at the antennae. The moth has feathery or saw-edged antennae, while the butterfly has antennae that look like a long shaft with a bulb at the end. In addition, moths and butterflies tend to hold their wings differently. Moths tend to fold their wings down to form a tent over their abdomen, hiding it from view. In contrast, butterflies usually hold their wings vertically up over their backs.
Both butterflies and moths develop through a process of complete metamorphosis with four stages: egg, larva, pupa, and adult. The young are very different from the adults and often eat different types of food. Pictures of the caterpillar larva for many of the species in this guide are included.

Additional information can be found in Butterflies through Binoculars: The West and Kaufman Field Guide to Butterflies of North America. Close-focusing binoculars are the best equipment for watching adult butterflies and moths.

Photo: Selvi Viswanathan Photo: Sam Kieschnick Photo: Selvi Viswanathan | Uncas Skipper(Hesperia uncas)Family: Hesperiidae (Skippers) Size: 1.1 - 1.6 in (3 - 4 cm) Color: black, brown Flits: May 15 - Aug 01 Status: native; common Food source: flower nectar Host: blue grama grass and needlegrass Habitat: open woodland, short grass areas The Uncas Skipper larvae build themselves shelters out of silk and plant materials. These shelters are expanded as the larvae grows. The adults are very strong fliers. They have such a fast wing beat that they can appear to be just a blur to the human eye. These butterflies only live for about three weeks and lose scales as they age. This causes their wing patterns to slowly disappear and the wings themselves to become duller. Info Photos |
Photo: Greg Lasley Photo: © Jim & Lynne Weber | Western Branded Skipper(Hesperia colorado)Family: Hesperidiidae (Skippers) Size: 0.9 - 1.4 in (2 - 3 cm) Color: orange Flits: Jun 15 - Aug 15 Status: native; uncommon Food source: nectar from asters and goldenrods as well as other flowers Host: grasses Habitat: open areas near forests and meadows The species is found across the globe with slightly different appearance depending on the particular geographical region. Thus there are several different recognized subspecies. In addition, Hesperia colorado is considered an entirely different species than the Common Branded Hairstreak Hesperia comma which looks similar but is darker in color. Info Photos |
