Caryocolum alsinella is a moth of the Gelechiidae family. It is found throughout Europe^[1] It is also present in North Africa (including Morocco).

The length of the forewings is 4–5 mm. The forewings are mid-brown, speckled with white, particularly across one-fifth and the middle. There are indistinct black markings. Adults have been recorded on wing from late June to late September.^[2]

The larvae feed on Arenaria montana, Cerastium arvense, Cerastium diffusum, Cerastium fontanum, Cerastium semidecandrum, Minuartia verna, Moehringia and Stellaria species. Young larvae mine the leaves of their host plant.^[3] Later, the larvae feed on young shoots, flowers and seed-capsules which are spun together. The larvae have a yellow or light green body and a black head. They occur in spring and pupation takes place up to the end of June.
