17 lis 2022 · Learn about the braconid wasps - their life cycle (eggs, larvae, cocoons), & benefits, what do they eat, & are they dangerous, along with pictures.

Perhaps the most widely recognized stage of any parasitoid wasp is the cluster of whitish/yellowish rice-like pupal cocoons of Cotesia spp. wasps (Braconids) found on tomato hornworms and cabbageworms.
