Butterfly and Moth Guide

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.

Achemon Sphinx

(Eumorpha achemon)

Family: Sphingidae (Sphinx Moths and Hawkmoths)
Size: 3.4 - 3.8 in (9 - 10 cm)
Color: brown, pink
Flits: Jun 01 - Jul 31

Status: native; common
Food source: nectar from flowers such as Jimpson weed and four o’clocks
Host: various vines and ivies
Habitat: wooded and scrubby habitats and inhabited areas

The adults usually only fly at night flitting between plants with fragrant flowers and long long flora tubes. They use their very long tongues to reach the nectar in the bottom of these flowers. There are three different colored forms of larvae: light green, reddish orange, and tan to brown. The larvae can often be seen in vineyards feeding on the vine leaves.

Western Popular Sphinx, Big Popular Sphinx

(Pachysphinx occidentalis)

Size: 5.2 - 5.8 in (13 - 15 cm)
Color: brown, yellow
Flits: May 15 - Sep 01

Status: native; common
Food source: adults do not feed
Host: cottonwood, poplar, and willow
Habitat: suburban and riparian areas

There are two colors forms of the Western Popular Sphinx, a pale form with yellow brown forewings and a dark form that is more gray. There is a touch of crimson on the upper-side of the hind wings along with two distinctive dark lines. Females lay their eggs on the leaves of Populus and Salix tree species.

White-lined Sphinx, Hummingbird Moth

(Hyles lineata)

Family: Sphingidae (Sphinx Moths and Hawkmoths)
Size: 2 - 3 in (5 - 8 cm)
Color: black, brown, pink, white
Flits: Jun 01 - Sep 30

Status: native; common
Food source: nectar from a variety of flowers including columbines, larkspurs, clovers, thistles and Jimson weed
Host: large range of trees and shrubs
Habitat: areas with flowers in full bloom

The White-lined Sphinx, as well as several other species, go by the nickname of “Hummingbird Moth” due to their rapid wing movement that resembles a hummingbird in flight. The adults primarily feed from dusk to dawn but occasionally can be seen during daylight hours. Although several generations of this moth may occur in a year, typically they are most obvious during July and August. Periodic population buildups occur stimulating emigrations to colonize new areas. Larvae can vary in color from yellow and black to lime green and black. When larvae are ready to pupate, they burrow into the soil and stay there for about three weeks before emerging as adults.
