Amphiagrion abbreviatum, the western red damsel, is a species of narrow-winged damselfly in the family Coenagrionidae. It is found in Central America and North America. The IUCN conservation status of Amphiagrion abbreviatum is "LC", least concern, with no immediate threat to the species' survival. The population is stable. The IUCN status was reviewed in 2017.
The western red damsel is primarily distributed across western North America, with records spanning four Canadian provinces, 23 U.S. states, and one state in Mexico. Its range extends from British Columbia and the northern prairies to the southwestern United States and Baja California.
Amphiagrion abbreviatum has long been considered a lentic species, typically found in marshes fed by springs and seepage areas in arid regions, as well as along the vegetated edges of ponds, lakes, and slow-moving streams. These calm, stable waters provide the perfect setting for larval development among submerged vegetation and allow adults to perch and oviposit without risk of being swept away. However, recent fieldwork in southern Alberta has revealed something unexpected: thriving, reproducing populations of... Wikipedia →

Rare
Under 5% of wildlife watchers report a Western Red Damsel sighting in Denver on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 352nd most-seen of the 461 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Western Red Damsel in Denver on a given day, so our monthly data shows no clear season.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Western Red Damsel sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Denver, in our data
Denver is the only city on Wallace's Line with enough records to rate Western Red Damsel sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Coenagrionidae
The closest relatives of the Western Red Damsel that you can see in Denver (family Coenagrionidae, Narrow-winged Damselflies) are Familiar Bluet (about 10%), Plains Forktail (about 10%) and Vivid Dancer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Western Red Damsel is recorded against all the insects logged in Denver (7 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
