Wednesday, April 22, 2015, 3:49 PM - Warmer weather means the return of cankerworms -- a tree-eating species whose larvae is popping up on foilage across Canada and the U.S.
Earlier this month, Regina, Sask. began banding trees in an effort to prevent female cankerworms from laying their eggs.
Known for their love of the heat, the damage cankerworms inflict on trees is most apparent during the summer months.

According to North Carolina State University, the caterpillars can devour the canopy of an oak tree in just two days' time.
They primarily feed on the leaves of American elms, Manitoba maple and Green ash trees.
Officials say the worms can cause thousands of dollars in damages. Trees that have been infected with the caterpillars are more susceptible to other diseases and insects.
In some states, U.S. officials have taken numerous steps to stop the spread of cankerworms -- including the use of aerial sprays -- but there appears to be no stopping them.
