In New Mexico, the most reliable moth on the wing through the warm season is the White-lined Sphinx (Hyles lineata), a large hawk moth that hovers at flowers at dusk and swarms lights statewide. Midsummer also brings the Zephyr io moth (Automeris zephyria), the five-spotted hawkmoth (Manduca quinquemaculatus), the western Pachysphinx (Pachysphinx occidentalis), and the Douglas-fir tussock moth (Orgyia pseudotsugata). By fall, watch for the Pandora moth (Coloradia pandora) and the buckmoth Hemileuca oliviae alongside the ever-present White-lined Sphinx.
What's flying in New Mexico right now
New Mexico spans desert, grassland, and high pine forest, and its moths track that range from sphinxes in the lowlands to conifer-feeding species in the mountains. The constant is the White-lined Sphinx (Hyles lineata), which appears in spring, summer, and fall and is the moth most New Mexicans notice as it nectars hummingbird-style at dusk.
In July the night gets dramatic. The Zephyr io moth (Automeris zephyria) is a southwestern io relative; like other io moths, its caterpillars carry urticating (stinging) spines, so do not handle them, while the adults show large hindwing eyespots. The five-spotted hawkmoth (Manduca quinquemaculatus) is here too; its caterpillar is the tomato hornworm, which is a different species from the tobacco hornworm of the Carolina sphinx. Rounding out summer are the big western Pachysphinx (Pachysphinx occidentalis), the tiger moths Hypercompe permaculata and Lophocampa ingens, the Douglas-fir tussock moth (Orgyia pseudotsugata), and the lichen moth Cisthene barnesii.
July vs. May vs. September
- May: spring is sphinx-led, with the White-lined Sphinx, the army cutworm moth (Euxoa auxiliaris), the tiger moth Lophocampa ingens, the western tent caterpillar moth (Malacosoma californica), and Melipotis indomita.
- July: peak diversity, with the Zephyr io moth, five-spotted hawkmoth, western Pachysphinx, Douglas-fir tussock moth, and White-lined Sphinx all on the wing.
- September: White-lined Sphinx persists, joined by the corn earworm moth (Helicoverpa zea), the high-country Pandora moth (Coloradia pandora), the fall webworm moth (Hyphantria cunea), and the range buckmoth Hemileuca oliviae.
Mothing tips for New Mexico
Elevation drives everything: a desert sheet and a mountain sheet on the same night can produce completely different moths. Moths respond most strongly to UV and short-wavelength light, and the leading explanation is that artificial light disrupts their flight orientation rather than acting as a goal, so a UV or mercury-vapor bulb over a white sheet beats a white LED. Warm, still nights after rain are excellent. Check the good-mothing-night score and the good-night-for-moths guide before heading out.

Frequently asked
What is the hummingbird-like moth in New Mexico?It is most likely the White-lined Sphinx (Hyles lineata), a large hawk moth that hovers at flowers at dusk and feeds on nectar. It is New Mexico's most commonly seen moth, active from spring through fall.
Are io moth caterpillars dangerous in New Mexico?The Zephyr io moth (Automeris zephyria) caterpillar has urticating, stinging spines, so do not handle it; the sting causes a painful rash. The adult moth, with its big hindwing eyespots, is harmless.
Is the tomato hornworm a moth in New Mexico?Yes. The tomato hornworm is the caterpillar of the five-spotted hawkmoth (Manduca quinquemaculatus), which flies in New Mexico in summer. It is a different species from the tobacco hornworm of the Carolina sphinx.
What moths fly in New Mexico's mountains versus the desert?High-country sites add conifer-feeding species like the Pandora moth and Douglas-fir tussock moth, while desert and grassland sheets favor the White-lined Sphinx, Pachysphinx, and buckmoths. Elevation makes a big difference on any given night.
Can this site identify a moth from a photo?No. It predicts likely species by your location and date from open GBIF records. For photo ID, use iNaturalist or Seek, BugGuide, the Moth Photographers Group, or BAMONA.
