Amblyderus pallens

Their body length ranges from 3.1 to 4.2 mm and their colour varies from yellow to light yellow and brown. Their back (dorsum) is lightly reticulated, though sometimes the head is smooth. This species has appressed body setae (hair), that is dense on their elytra. Lastly, A. pallens has reduced flight wings.

Amblyderus pallens live in dune and sandy beach habitats. The adults are found in the sand hiding under plants and debris like beach drift and also among grass roots up to 4–8 cm under the surface. They are usually found between May and August, but can also be active from November to February. In Canada, they have been recorded in Alberta, Saskatchewan, Manitoba, Ontario, Quebec, and News Brunswick. More recently, they have been discovered in Nova Scotia and Prince Edward Island. In the United States, they have been recorded in Arizona, Colorado, Florida, Georgia, Illinois, Indiana, Louisiana, Maine, Massachusetts, Michigan, Mississippi, Missouri, Nebraska, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Oklahoma, South Carolina, South Dakota, Texas, Virginia, and Wisconsin.
