Unwelcome visitors

I've been waiting for the return of the so-called "winter moths": those incredibly destructive leaf defoliators whose adults emerge from pupation sometime in November to flock to the cedar shingles by the kitchen door and, more to the point, the trees surrounding the house. From there, Operophtera brumata adults will, despite the chill, pursue mating opportunities. For now, however, the vanguard of the introduced pests, which first appeared in North America in the 1930s when a population of the European and Asian species gained a foothold in Nova Scotia, are laying low... and waiting for the magical scent of female pheromones that say, without any doubt of the message, I'm available.
