context_page_description: Coelopa pilipes is a common European species of kelp fly. It was described by A. H. Haliday in 1838. Their appearance differs greatly from that of other Coelopa flies.
  C. pilipes are especially prevalent in European beaches. Year-round, these flies live in washed-up kelp on wrack zones of beaches before adulthood and consume the decaying kelp, mostly of the genera Laminaria and Fucus that have a great impact on the flies' survival. Female flies lay eggs in the decaying seaweed, and larvae mature in the warm, moist environment it provides. C. pilipes has significant sympatry with C. frigida; the two flies are often studied together due to their overlapping habitats and distribution.
context_section_description: Larvae of C. pilipes feed on the same decomposing seaweed their eggs are deposited on. They may also consume bacteria found on the surface of the seaweed. If only raised on Laminaria seaweed, the flies have reduced growth due to a lower nutritious value of seaweed. The Fucus seaweed that the flies prefer most is prevalent in the North Pacific. The presence of Fucus can be associated with the number of C. pilipes flies at a certain site.
