Sighting Record 1193768

Observation Notes: 
This moth was on a dirt road at about 9,000ft. The weather was sunny and was probably in the 60sF. The moth was resting on the dirt, and would flutter and change position if approached too closely. There had already been a first snow of 6", which by the time of the siting had nearly completely melted.

Sighting Record 1193413

Observation Notes: 
Time: ~2:45 p.m. Temperature: 67 degrees. Wind: 7 mph. Sky: Sunny. Habitat: Rendezvous Trail, a combination of semi-riparian and “weedy field” habitats. Notes: I observed three Orange Sulphurs along the Rendezvous Trail. There were large colonies of still-green legumes (I believe milkvetches) growing all along the trail, probably explaining the late-flying sulphurs in the area.

Sighting Record 1193403

Observation Notes: 
Time: ~4:00 p.m. Weather: Very hot, fairly calm, and partly cloudy. Habitat: In a residential area; small, dry ditch consisting of mostly grasses and "weedy" plants (dandelions, hoary cress, lamb's ears, thistles, mallow, morning glories, etc.). Notes: A large Black Swallowtail resided behind my house (mostly in the ditch area) for a couple days (July 8-9). During that time, I sighted it on four different occasions. On the second occasion (July 8), I ran alongside it for long enough to confirm identification as Papilio polyxenes.

Sighting Record 1193401

Observation Notes: 
Time: ~1:45 p.m. Temperature: 58.15 degrees. Wind: 8 mph. Sky: Partly cloudy. Habitat: Typical riparian habitat (cottonwoods, dandelions, grasses, legumes, showy milkweed, willows, etc.). Notes: A Milbert's Tortoiseshell landed on the ground by a large group of Showy Milkweed near a subchannel of the Poudre River, dorsally basking itself in the sun. Unfortunately, it flew away before I could capture or photograph it.

Sighting Record 1193378

Observation Notes: 
Time: 1:11 p.m. Weather: Warm, fairly calm, and mostly cloudy (it rained at one point). Habitat: Very dry upland prairie. Notes: This Variegated Fritillary was nectaring on a flowering rabbitbrush right at the start of the Well Gulch Trail. Most of the other fritillaries in the area were Speyeria sp., but none of them landed long enough to be photographed.

Sighting Record 1193377

Observation Notes: 
Time: 3:32 p.m. Weather: Warm, fairly calm, and mostly cloudy (it rained at one point). Habitat: Very dry upland prairie, with fully blooming rabbitbrushes densely lining both sides of the gravel road. Notes: This moth was nectaring on a rabbitbrush at the edge of a gravel road. It is definitely a noctuid, and the reddish-mahogany color on the dorsal side might be distinctive.

Sighting Record 1193375

Observation Notes: 
Time: 2:43 p.m. Weather: Warm, fairly calm, and mostly cloudy (it rained at one point). Habitat: Sparse coniferous forest. Notes: I came across this small red moth(first three photos) nectaring at an extremely isolated flowering rabbitbrush (fourth photo) high up on the Well Gulch Trail, within coniferous forest habitat. Using iNaturalist and internet searches, I could not find any species of moth that even remotely resembles this one.

Sighting Record 1193374

Observation Notes: 
Time: 3:31 p.m. Weather: Warm, fairly calm, and mostly cloudy (it rained at one point). Habitat: Very dry upland prairie, with fully blooming rabbitbrushes densely lining both sides of the gravel road. Notes: This moth was nectaring on a rabbitbrush at the edge of a gravel road. Again, it looks quite similar to the Corn Earworm Moth, but I'm not sure of ID.
