Advertisement Hi, I recently visited Canada's arctic territory, the Northwest Territories, which is mostly taiga and tundra. My mother and I went to Wood Buffalo National Park there and, I must say, I am amazed at the diversity of flying insects. Never have I been to a land with more horseflies, dragonflies, mosquitoes, gnats, damselflies, deer flies, black flies, etc. I've read in books that the Russian taiga is horrid for flies in the summer. Well now I've got a taste of it (literally, there were so many flies you'd breath them in). What makes the taiga so perfect for flying insects? I would have thought that the cold temperatures would have made it more or less fly free.
