Dicosmoecus gilvipes is a species of northern caddisfly in the family Limnephilidae. This particular caddisfly is found in and near streams of North America, from northern California and Colorado to British Columbia and as eastern to Nevada, Idaho, Montana and Alberta. D. gilvipes is commonly known as the October Caddis, Autumn Caddis or Giant Orange Sedge, due to their flying presence acknowledged in the Autumn. Caddisflies are known to build cases when they are in larvae stages, to protect themselves from predators, such as dragonflies, salmon and trout. The October Caddisfly is no different and builds their cases out of different organic materials during their five larvae stages.
D. gilvipes occur in the Nearctic and eastern Palaearctic regions. This species can be found in and near streams within mid-elevations. Males fly more often than females, due to the release of pheromones produced by the females. Females limit flying to make their pheromone trail more apparent to the males for mating. Copulation between mating pairs can last up to 16 hours, and the pair stay together until throughout the attraction period to ensure... Wikipedia →

No species of the same family or order lives in Olympic National Park, so these are its closest relatives here: other insects.
Rare
Under 5% of wildlife watchers report a Dicosmoecus gilvipes sighting in Olympic National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 182nd most-seen of the 207 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.
June and October–November
In those months about 10% of wildlife watchers report a Dicosmoecus gilvipes in Olympic National Park on a given day, against under 5% in July–September and December–May, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Dicosmoecus gilvipes sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Olympic National Park, in our data
Olympic National Park is the only park on Wallace's Line with enough records to rate Dicosmoecus gilvipes sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Dicosmoecus gilvipes is recorded against all the insects logged in Olympic National Park (5 verified sightings from 2019 to 2026), 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.
