Unlike their bee and wasp relatives, sawflies are plant eaters, named for the way females use their egg-laying organs to saw slits in plants. Adult sawflies look like wasps, but they don’t have a constricted waist, nor do they sting. They don’t feed on plants it’s the larvae that do the damage. The various sawfly species include the cherry sawfly, pear slug, rose slug, and European pine sawfly, each pest attacks a narrow range of hosts. Larvae of the ”slug” type do look like little slugs, complete with slime coating; other types resemble multi-legged caterpillars.
