Walnut Husk Fly
A fruit fly whose larvae feed inside walnut husks, staining and damaging the nuts. It has become an invasive pest in European walnut-growing regions.
Did You Know?
Larval feeding stains walnut shells black, making them unmarketable even though the nut inside may be fine.
Social Pear Sawfly
A broad-bodied sawfly with long antennae whose larvae spin communal webs on pear and other fruit trees. Multiple larvae feed together within the silk nest.
Did You Know?
The larvae build elaborate communal silk nests that can envelope entire branch clusters, creating conspicuous webbed masses on fruit trees.
