One of the hoop houses has a healthy population of Swift Forktails, a type of damselfly. Swift Forktails are black with dabs of turquoise on the tips of their tails and their sides. They float through the air looking like flying gems.
Related to dragonflies, damselflies eat many harmful insects and keep their numbers under control. And unlike pesticides, they don’t leave behind any chemicals that can harm you. You don’t have to worry about inhaling any harmful dust. You don’t have to worry about reapplying poisons. The damselflies will keep working all summer long and into the fall.
