Garden To-Do’s – Beneficial Insects

One of the great things about our dry, warm April is the burgeoning population of insects. Yikes! Am I crazy? Nope; when prey insect numbers rise, predator insects have plenty to eat. That’s a great thing for gardeners because predators help us keep down pesticide use.

For example, let’s say we want to have plenty of ladybugs, syrphid fly larvae, and tiny parasitic wasps in our garden so as to control aphids on our veggies. Having lots of prey will increase predator populations, so we can plant something ornamental that will grow aphids, like . . . a crape myrtle. Crape myrtles attract aphids, and it doesn’t seem to bother them much, although sometimes the sticky exudate from the aphids can be annoying to humans. (That’s one reason crape myrtles are best planted out in the landscape.)

Another plant that supports beneficial insects is sunflowers. Some beneficial adults are predators (like ladybugs), but other adults depend on pollen or nectar for lunch. A nice patch of native dune sunflowers will keep beneficial wasp adults healthy and happy. Once you’ve planted your flowers, may I suggest a great project for a cool April morning? Why not construct a pollinator hotel to attract our sweet-tempered, native bees?
