  • The larvae feed on algae and other organic matter in the water. (boatboatgo.com)
  • This symbiotic relationship indicates a specific adaptation, as fresh-flowing streams could not provide sufficient nutrition to the growing larva in any other way. (wikipedia.org)

  • BF larvae are superbly adapted for staying in place and feeding underwater without being swept away by the current. (riveredgenaturecenter.org)
  • The susceptibility of mustard beetle, Phaedon cochleariae, larvae to the insect pathogenic fungus Metarhizium anisopliae, was influenced by the topography of the host plant, the dosage and the larval instar. (rothamsted.ac.uk)
