The Canadian National Collection (CNC) of Insects, Arachnids and Nematodes
The Canadian National Collection (CNC) of Insects, Arachnids and Nematodes
is considered one of the best collections of its kind in the world in
terms of size, species representation, and level of curation. It is maintained
and developed by Agriculture and Agri-Food Canada as part of its systematics
research program, and is housed in the K.W. Neatby Building of the Eastern
Cereal and Oilseed Research Centre in Ottawa (Figure
1). The collection is estimated to contain approximately 16 million
specimens systematically arranged in 1400 steel cabinets (Figure
2). Specimens are stored mostly as dry-mounted pinned specimens (Figure
3), but certain groups (e.g. larvae, aquatic insects, spiders, mites,
aphids, midges, fleas, etc) are stored in liquid preservative (Figure
4) or mounted on slides (Figure 5). The
majority of specimens are from localities throughout Canada and the rest
of North America, but significant holdings are present from other biogeographic
regions.
