Yellowjacket

Yellowjacket is the common name for wasps in the genera Vespula and Dolichovespula. They belong to the insect family Vespidae in the order Hymenoptera, which also includes other types of wasps such as hornets, as well as bees and ants. Worldwide, there are about 50 recognized species of yellowjacket, 17 of which are native to Canada. These native species include the common (Vespula alascensis), Eastern (V. maculifrons), Western (V. pensylvanica) and aerial (Dolichovespula arenaria) yellowjacket. One species, the German yellowjacket (V. germanica), is introduced to Canada and is especially common in Ontario and Quebec.

Whale Species in Canada

Whale is the common name for large marine mammals of the order Cetartiodactyla (formerly Cetacea). They are subdivided into the Mysticeti, or baleen whales, and Odontoceti, or toothed whales. Smaller kinds of toothed whales are called dolphins or porpoises. Thirty-five whale species are found at least occasionally in Canadian waters — 9 species of baleen whales, and 26 species of toothed whales (mostly dolphins and porpoises). The commercial pursuit of whales was significant in early European exploration of Canada (see Whaling). Since the end of commercial whaling in Canada in 1972, whale watching has become popular. Whales found in Canada range in size from about 60 kg for the harbour porpoise to well over 100 tonnes for the blue whale, making it the largest animal ever known.
