Recent Status: A rare coastal species.

Life Style: A single brooded summer flying species that comes to light. The larvae feed on a variety of Cerastium species in sandy locations. They initially mine the leaves and then feed from spinnings on the shoots, flowers and seed capsules. They pupate in a sand covered cocoon on the ground.

Identification: Caryocolum species can be difficult to identify. C. alsinella is marked with black, white and brown with a specific pattern but is variable in the balance and extent of the markings. More Info When the pattern cannot be clearly seen in a specimen then genitalia dissection is required for identification. More Info
