Area of Science:

  • Entomology
  • Biodiversity Studies
  • Canadian Fauna

Background:

  • The Raphidioptera, or snakeflies, are a poorly understood insect order.
  • Previous assessments of Canadian Raphidioptera were conducted in 1979.
  • Current knowledge of Raphidioptera diversity in Canada is limited.

Purpose of the Study:

  • To update the species inventory of Raphidioptera in Canada.
  • To assess the current diversity and distribution of Raphidioptera in Canada.
  • To identify potential new species of Raphidioptera in Canada.

Main Methods:

  • Review of existing taxonomic literature and museum collections.
  • Analysis of DNA barcode data from specimens collected in Canada.
  • Comparison of Canadian Raphidioptera records with international databases.

Main Results:

  • Eight species of Raphidioptera in two families are currently known from Canada.
  • This represents an increase of one species since the 1979 assessment.
  • DNA evidence and distributional records suggest four additional species are likely present in Canada.

Conclusions:

  • The diversity of Canadian Raphidioptera has increased since 1979.
  • Further research is needed to confirm the presence of the four suspected species.
  • The Barcode of Life Data System currently lists ten Barcode Index Numbers for Canadian Raphidioptera, indicating ongoing research and discovery.
