Instructions
Recognize the venomous black widow. Of the five widow spiders indigenous to North America, two trek inside Canada's borders. Those are the Latrodectus hesperus, or western widow, and the Latrocdectus variolus, or northern widow. The female of the latter has three reddish or yellow dots on its abdomen and several white stripes alongside the dots. The western widow has a red "hourglass" shape on its belly. While the females are jet black in color, the males of both species are about half the size of their counterpart and appear tan.
Become knowledgeable about tarantulas. Tarantulas are fairly uncommon in Canada. Only those in the genus Aphonopelma have been found north of the U.S. border, mostly in the Pacific Northwestern region. Tarantulas carry a common stigma and menacing appearance. However, there has never been a documented fatality from a tarantula bite worldwide. Experts equate tarantula bites to a wasp sting. The Brazilian wandering spider, one of the world's most venomous spiders, is often mistaken for a tarantula; these spiders do not appear in Canada.
Know common spider types found in Canada. There is an abundance of more common spider types found throughout Canada. More than 700 spider species are found in British Columbia alone. One such spider is the wolf spider, which eats insects and, in some genus varieties, carries its young on its back. Another generally recognized spider found in Canada is the Corinnid sac spider, which is a wanderer. It has yellow lines that run parallel on its abdomen, similar to yellow passing lines along a highway. The hairy and unusual Lynx spider is bountiful in Canada; it preys on insects by living on leaves. But its green cousin has never been spotted in Canada.
