Moths in Nevada: What's Flying Tonight

In Nevada, the most reliable moth on the wing across the warm season is the White-lined Sphinx (Hyles lineata), a large, fast hawk moth that hovers at flowers at dusk and turns up at lights statewide. In midsummer it shares the night with the tiger moth Spilosoma vagans, the green-and-cream day-flyer Gnophaela latipennis, the sphinx Sphinx vashti, and small pyralid-style moths like Mimoschinia rufofascialis. By fall, look for the spotted tussock moth (Lophocampa maculata) and the buckmoth Hemileuca neumoegeni joining the White-lined Sphinx.

What's flying in Nevada right now

Nevada is high desert and Great Basin sage country, and its moth life reflects that: fewer of the giant silk moths of the East, and more drought-adapted sphinx moths, tiger moths, and small flower-tied species. The constant through spring, summer, and fall is the White-lined Sphinx (Hyles lineata), which appears in all three peak windows and is the moth most Nevadans notice first, often mistaking it for a hummingbird as it nectars at dusk.

In July the supporting cast includes the wandering tiger moth (Spilosoma vagans), Sphinx vashti, the day-flying Gnophaela latipennis, and several small, intricately patterned moths such as Mimoschinia rufofascialis, Pyrausta semirubralis, and the sulphur-toned geometrid Hesperumia sulphuraria. The puss-moth relative Furcula scolopendrina also shows up at sheets.

July vs. May vs. September

• May: dominated by the White-lined Sphinx and Spilosoma vagans, with the western tent caterpillar moth (Malacosoma californica), Schinia ligeae, and Egira perlubens rounding out spring.
• July: the most diverse window, adding Gnophaela latipennis, Sphinx vashti, Hesperumia sulphuraria, Furcula scolopendrina, and the small Pyrausta and Mimoschinia moths.
• September: White-lined Sphinx is still going strong, now joined by the spotted tussock moth (Lophocampa maculata), the dart Fishia discors, and the buckmoth Hemileuca neumoegeni.

Mothing tips for Nevada

Desert nights cool fast, so the prime window is the first couple of warm hours after dusk. Moths come to UV and short-wavelength light most strongly. The leading explanation is that artificial light disrupts their flight orientation rather than drawing them in like a goal, so a UV or mercury-vapor bulb over a white sheet far outperforms a white LED. Sheltered washes, riparian strips, and blooming desert plants concentrate activity in otherwise sparse terrain.
