Yellowjackets Roll Tiny Meatballs For The Babies | Deep Look

Why is that yellowjacket crashing your BBQ? Well, she wants what you're having: burgers, hot dogs, fish and turkey. But she doesn't eat them herself. Her nest's larvae need that protein to develop. So she carves up your dinner and makes teeny-tiny meatballs for them.

See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small. -- Yellowjackets bring back all kinds of interesting fare to their nests. The scavenging species might make meatballs out of moth wings, cockroaches or pieces of carrion. And all that food gathering and flying around gives adult yellowjackets an appetite. After delivering scavenged foods to the larvae, adult yellowjackets prod the youngsters and they offer their thanks in the form of a sugary throw up, or exudate. The adults slurp that up and jet off on more meatball missions. ---+ Are yellowjackets pollinators? Yellowjackets are pollinators! They visit flowers to gather sugary nectar that helps fuel their flight. They’re not as good at pollinating plants as bees are because their bodies are less hairy so they don’t pick up as much pollen. ---+ Do yellowjackets die after they sting? Yellowjackets do not die after they sting. They can sting multiple times, but it’s a last resort when they are threatened. ---+ Find additional resources and a transcript on KQED Science: Link TK Monday a.m. ---+ Busy Bees and Other Pollinators Playlist: https://www.youtube.com/watch?v=XjOfbEWVBpE&list=PLdKlciEDdCQCfoI8E24mbuk259unmiwG9 GIF CHALLENGE WINNERS: We're checking the answers with our scientists - will post shortly! ---+ Thank you to our Top Patreon Supporters ($10+ per month)!
