Beneficial insects of Canada



A cover from Canada with the low definitives of 2007 - a swarm of insects ! 

They skitter, scamper, and sometimes sting; we call them bugs for our own reasons. But, as any veteran gardener will tell you, one person’s pest is another person’s helper.


In 2010, Canada Post  celebrated five more of nature’s tiniest helpers: the paper wasp (Polistes fuscatus), the assassin bug (Zelus luridus), the large milkweed bug (Oncopeltus fasciatus), the margined leatherwing (Chauliognathus marginatus) and the dogbane beetle (Chrysochus auratus).

Wildflower gardeners and farmers may appreciate the large milkweed bug for feeding on the juice from milkweed seeds

Margined leatherwings

Margined Leatherwings are a type of Soldier Beetle. Adults can be found in the spring on the blossoms of a variety of flowers such as hydrangea, linden, New Jersey tea and tree of heaven. They roam into and out of blossoms, inadvertently covering themselves in pollen. This makes them great pollinators in gardens, fields and meadows. The stamp has some interesting security elements ! 




 The dogbane beetle of eastern North America, is a member of the insect subfamily Eumolpinae. It is primarily found east of the Rocky Mountains. One of the brightest in its family, it is iridescent blue-green with a metallic copper, golden or crimson shine. Its diet mainly consists of dogbane and milkweed.

Canada Post issued a 22¢ Monarch Butterfly stamp March 31 to serve as a make-up rate stamp for the country’s new postage rates.Canada’s domestic letter rate increased dramatically on that date, changing from 63¢ to 85¢, in 2014.

Hyalophora cecropia, the cecropia moth, is North America's largest native moth. It is a member of the family Saturniidae, or giant silk moths. Females have been documented with a wingspan of five to seven inches (160 mm) or more. These moths can be found all across North America as far west as Washington and north into the majority of Canadian provinces. Cecropia moth larvae are most commonly found on maple trees, but they have also been found on cherry and birch trees among many others.
