This is the highest known body fat percentage of any animal. ![]() ![]() Army cutworms are one of the richest foods for predators, such as brown bears, in this ecosystem, where up to 72 per cent of the moth's body weight is fat, thus making it more calorie-rich than elk or deer. They are known to travel to alpine climate regions in late June and early July where they feed at night on the nectar of wildflowers. Location Įuxoa auxiliaris is commonly found in the Western section and prairies of the United States. However, other than being a nuisance, they are not considered harmful. ![]() With their very small bodies, they enter homes (attracted by the light) in the evening through any available crack or crevice (doorjamb, chimney, etc.) and residents in migration paths report dozens of moths per day entering their homes and garages. They are considered nearly impossible to control through normal pest extermination techniques because a new batch shows up every day as they migrate. They return as the weather cools but in smaller numbers. The miller moth is a seasonal nuisance in the spring in states including Texas, Oklahoma, Colorado, Wyoming, New Mexico, and Kansas, as they hatch in the low-lying farmlands, then migrate to higher elevations for the summer. Intermountain West, army cutworms consume exotic cheatgrass ( Bromus tectorum) and mustards to produce cheatgrass "die-offs." Within these bare areas, the larvae also defoliate native shrubs including four-wing saltbush ( Atriplex canescens) and sagebrush ( Artemisia spp.). On dry, low elevation rangelands of the U.S. Larvae feed above ground at night and usually hide in soil during daylight, but will also feed on cloudy days. These native North American larvae consume emerging small grains, alfalfa, and canola in the southern Great Plains and southern Canada. ![]()
