Basil-thyme case-bearer moth  (Coleophora tricolor)

In early autumn, the caterpillars initially feed within the seedheads of basil-thyme (Acinos arvensis). As they age, they move to feed on grasses, where they spend the winter, still protected inside their cases. They feed again during the following spring when they construct a new case from the cuticles of blades of grass (5), before pupating. Adults fly during July and early August (2).
