These appear to be aphids, or more accurately, shed aphid skins (which are white and shriveled), since live aphids are plump and often green (though can be a variety of colors). Aphids are a very common nuisance pest on vegetables and other plants, though they rarely cause plants serious damage. The easiest method for removal is squishing them by hand or blasting them off foliage with a strong spray of plain water, either using a garden hose or sink faucet sprayer. If needed, low-toxicity pesticides can be used to knock-down an abundant population, such as horticultural oil or insecticidal soap. More than one treatment of the water spray or pesticide will likely be needed since aphids are small and easy to miss (and able to reproduce rapidly); follow all product label instructions if using a pesticide, and make sure it's also labeled for use indoors or in greenhouses and for use on edible plants.

When I put them under the microscope, I initially thought they looked like aphids, but the shape wasn't right.  Makes sense that they are the shed skins.   

Thank you.

You're welcome.
