May 28 Quiz — Insect ID

May 28, 2015 - Issue 11

Many, many insect species are present in canola fields, and only a few of them are pests. Erl Svendsen with AAFC in Saskatoon provided the five insect photos below.

For this week’s quiz, try to determine whether these insects are friend or foe. These are a little more challenging than other insect ID quizzes we’ve had in the past, and even some of these “foes” would rarely warrant a spray because they’re just not that common and rarely at numbers that would justify control.
