Do you ever wonder if that insect on your flowers is good or bad? Check out these insects.
Before you swat the striped insect on the flower — half the time it's not even what you think.
Mid-May is when pollinators and stinging wasps both peak in the same garden. They look similar, they're near the same flowers, and most people react before they look. Some of the most wasp-like insects can't sting at all. And among the actual wasps, most are valuable predators when their nests aren't in your walkway.
🌿 Leave these — they're pollinating your garden:
- Honeybee — golden-brown body with darker bands, fuzzy, often carrying visible orange pollen on the hind legs. Calm unless directly threatened. Visits almost every flower in the garden
- Bumblebee — large, very fuzzy, black with yellow bands. She vibrates certain flowers — tomatoes, blueberries, peppers — at a specific frequency to shake pollen loose. No other common pollinator does this. Native species and worth protecting
- Mason bee — solitary native bee with a metallic blue-black body, about honeybee-sized. Nests in hollow stems, not hives. Doesn't swarm, doesn't defend territory. Pollinates far more effectively per individual than a honeybee because she's messier — pollen falls off her belly at every stop
- Hover fly — looks like a small wasp but is a fly with no stinger. Two wings instead of four, huge eyes, hovers perfectly still then darts. The larvae eat aphids. She's wearing a wasp costume she borrowed and never pays for
🐝 Be aware of these — beneficial predators, but give nests distance:
- Yellowjacket — sleek bright-yellow-and-black bands, narrow waist, much less fuzzy than a bee. Ground or wall nests. She's a beneficial predator of flies and caterpillars through spring and summer. Late summer is the aggressive window — the colony shifts to scavenging sweet food and drinks. Give ground nests a wide berth; only remove if the entrance is in a high-traffic path
- Bald-faced hornet — large black body with white face markings. Basketball-sized gray paper nests hanging from branches or eaves. Voracious predator of flies all summer. Aggressive only near the nest — largely indifferent at a distance. Locate the nest and give it space; remove only if it's near a doorway or play area
- European paper wasp — yellow-and-black banded with long legs dangling in flight. Invasive across most of the US. Important detail for butterfly gardeners: paper wasps are significant predators of monarch caterpillars. If you're growing milkweed for monarchs, remove paper wasp nests nearby. In areas without butterfly habitat, the nests can stay — the wasps eat other garden pests
- European hornet — large brown-and-yellow, active at night around porch lights. Less aggressive than yellowjackets. Reducing outdoor lighting at night limits attraction
🌱 The one-second read:
- Hovering perfectly still over a flower = hover fly. Can't sting
- Fuzzy and round on a flower = bee. Not defensive while feeding
- Sleek with a narrow waist near a ground hole or wall gap = yellowjacket. Give the nest distance
- Aggressive flying-at-your-face = you're near a nest. Back away calmly. Don't swat — swatting triggers defense pheromones that bring more
Also in your garden and mostly harmless: carpenter bees, metallic green sweat bees, leafcutter bees that cut neat circles from rose leaves for their nests, and dozens of solitary natives that don't swarm or defend.
The pollinator and the stinger wear the same stripes. The difference takes one second to read 🌿
