Cocoa moth

The cocoa moth (Ephestia elutella) is a small moth in the family Pyralidae with a wingspan of 14–22 millimetres, cosmopolitan in distribution as a stored-product pest. The species is native to Europe but has spread globally through trade in stored commodities, particularly cocoa beans (from which its common name derives), dried fruits, tobacco, grain, nuts, and confectionery. Adults are greyish-brown with subtle patterning on the forewings; they are short-lived and do not feed as adults. Females lay eggs directly in or near food material; larvae are creamy-white with dark head capsules and spin silken webbing through infested commodities as they feed, causing significant post-harvest economic losses. Like other pyralid stored-product moths, E. elutella is a major pest of food processing and warehousing facilities worldwide, thriving in warm, dry storage conditions with high carbohydrate content. It has been recorded from at least 30 European countries and is present on all inhabited continents. Control relies on temperature treatment, pheromone-baited monitoring traps, and chemical insecticides, though resistance to some compounds has been reported. The species is classified as Least Concern by the IUCN, reflecting its global distribution and thriving populations in human-modified environments. Its economic importance has made it the subject of extensive research into stored-product pest biology, chemical ecology, and integrated pest management strategies.

Common Least Skipper

The Common Least Skipper (<em>Ancyloxypha numitor</em>) is a small butterfly in the family Hesperiidae, classified as Least Concern on the IUCN Red List. It is native to Canada and the United States, where it typically inhabits virtually all terrestrial and freshwater habitats within its range, showing a particular affinity for moist, grassy areas near water. The species is among the smallest skippers in North America, characterized by orange and brown wing coloration and a rapid, low-flying flight pattern close to vegetation. Adults typically nectar on small flowers while larvae feed on grasses, particularly those in wet meadows, marshes, stream margins, and disturbed grassy areas. The Common Least Skipper is frequently observed in wetland margins, wet prairies, and roadsides with rank grass growth. Its wide distribution across North America and habitat generalism across moist grassland and wetland types support its stable population and Least Concern conservation status. Biological traits of this species remain poorly documented in the scientific literature.
