Beware of this giant, ‘toe-biting’ water bug this summer
This is the biggest aquatic insect in Canada
The next time you hop into a lake and feel a painful pinch on your toe, it could be a giant water bug.
These bugs, also known as Lethocerus americanus, belong to the Belostomatidae family. They are native to southern Canada and the U.S. and can be found in British Columbia, Alberta, Ontario, Nova Scotia and Quebec.
Typically measuring 5–6 cm, they are the largest aquatic insects in Canada. They are flattened, brownish, piercing-sucking insects that can be seen from June to November. In winter, they burrow into plant debris and mud.
