Quebec joins the club, caterpillar reports filling in
Reports of monarch larvae are inching northward.
Our northernmost report of a caterpillar comes from Thunder Bay, Ontario, on June 18 at latitude 48.4, and we’ve received our first reports of larvae from South Dakota and North Dakota over the past two weeks as well.
Some western sightings provide ‘beacon of hope’
Despite the small number of overwintering monarchs along the California coast this winter, there is a sigh of relief as monarchs are appearing in many western states. Hope is in the air as monarchs reach their summer breeding grounds for ideal weather conditions so their numbers will increase exponentially over the next several months.
