The plant-arthropod interactions of a native carnivorous plant, the English sundew, Drosera anglica Hudson, were studied in the Nisbet Provincial Forest of central Saskatchewan, Canada during July–August 2000 and June–August 2001. The principal insect groups collected from sundew leaves were biting and predaceous midges (Diptera: Ceratopogonidae) and non-biting midges (Chironomidae), in nearly equal proportions. More than 1,600 individuals of each of these primitive flies were collected each year, with each family representing 30–35% of total identifiable prey. Fifteen species of ceratopogonids were identified in seven genera, with the majority (75.7%) being either Atrichopogon websteri (Coquillett) or Dasyhelea spp. The overall sex ratio of ceratopogonids was 15∶1, females to males.
