I've
been dutifully plucking asparagus
beetles and squashing eggs once a week, hoping that a predator will
show up soon and take over. By now, the eggs I missed have given
way to plump larvae nibbling on asparagus fronds, so I was thrilled to
suddenly notice half a dozen insects I'm unfamiliar with sharing the
habitat. Could this be my long-awaited pest control?
Sadly, no. The new
bugs are just some of the seemingly unlimited supply of different native
pollinators in our
garden, these attracted to the just opened asparagus blooms. The
scary looking guy at the top of the page is a Syrphid Fly (aka Hover
Fly) that feeds on nectar as an adult and on moist organic debris as a
larva. The strange percher on the right is a Thick-headed Fly
taking a break from a snack of nectar before she lays her eggs on a
bumblebee or wasp in flight.
I'm still rooting for a
predacious wasp, but until I see one I'll keep squashing beetle larvae.
