Walnut Husk Fly

Walnut Husk Fly Description: about the size of a housefly and very colorful. It has a yellow spot just below the areas where the wings are attached and iridescent, greenish eyes. The wings have three prominent dark bands, one of which extends around the wing to form a V-shape. The banded wings distinguish it from other flies found in the walnut orchard. Larvae feed in groups within the husk and are not seen unless the skin of the damaged husk is removed. Dark, soft blotches on maturing husks are a good clue to husk fly presence.

Cause Damage To: The primary damage from the husk fly is staining of the nutshell, which is a problem in commercial orchards where nuts are grown for in-shell sale, but can be tolerated in backyard situations. Feeding by the husk fly maggots also causes the damaged husks to stick to the shell, making them difficult to remove. An early-season husk fly infestation (June to mid-August) may result in shriveled, moldy kernels.

Whiteflies

Whiteflies Description: Tiny, snow-white insect pests that (when viewed under a magnifying glass) resemble moths.

Yellow Jackets

Yellow Jackets Description: Most of these are black-and-yellow; some are black-and-white, while others may have the abdomen background color red instead of black. They can be identified by their distinctive markings, small size, their occurrence only in colonies, and a characteristic, rapid, side to side flight pattern prior to landing. They are often mistakenly called "bees".
Cause Damage To: considered quite beneficial to agriculture since they feed abundantly on harmful flies and caterpillars, it is their boldness (sometimes aggressiveness) and painful stinging ability that cause most concern.
