Bristly Rose Slugs

Photos again thanks to Carole. They might be small but these Bristly Rose Slugs (sawfly larvae) can do some serious damage to a rose in a short amount of time. Control for these little buggers include hand removal, neem oil or insecticidal soaps. See below for some links to more info.



Japanese Beetle
