Contents: By Damage and Image
In May, one can spot cutworm
damage in the landscape on Dutch iris. The caterpillars take an almost
sadistic pleasure in waiting until the irises are nearly ready to flower
before they strike. They tunnel into the swollen buds to dine on the rich
resources there. Or true to name, they wait until after the blossoms unfurl,
then play logger, chomping into the stem, felling the iris. Timber.
