Bumble Bees
Bombus spp.
Apidae · Genus Bombus
Big, fuzzy, striped, social bees — the ones everyone recognizes. Bumble bees are the most efficient pollinators in New Jersey and the only bees here that can buzz-pollinate: vibrating their flight muscles at a specific pitch to shake pollen loose from flowers that lock it away.
How to spot one.
Round furry body, 0.5–1 inch
Distinct color bands — yellow, black, sometimes orange
Slow, loud flight — you can hear one coming
Legs carry visible packed pollen baskets on the hind legs
How it lives.
Annual social colonies of 50–500 workers, founded in spring by a single overwintered queen. Nests in abandoned rodent burrows, tussock grass, hollow logs, or brush piles. Only new queens survive the winter — everyone else dies with the frost.

Buzz-pollinator
The Rusty-patched Bumble Bee (Bombus affinis) was once common across NJ. It has been considered locally extinct from the state since the late 1990s, and was federally listed as Endangered in 2017 — the first bumble bee in the continental US to receive that protection. Other native bumble bees are declining, largely from habitat loss, pesticides, and pathogen spillover from managed honey bees.
