Yarrow, yarrow, yarrow.
Drone fly, drone fly, drone fly.
This little insect is often mistaken for a honey bee. In the adult stage, both the drone fly and honey bee nectar flowers. However, the drone fly is a syrphid fly (family Syrphidae, subfamily Eristalinae, tribe Eristalini, genus, Eristalis). Like all syrphids, it has two wings. The honey bee has four.
Other distinct differences tell you it's a fly, not a bee. It's amazing, though, how often stock photos proclaim "honey bee" when the insect is actually a drone fly.
In its larval stage, the drone fly is known as a rat-tailed maggot. You'll see it in stagnant water, such as in ditches, ponds and drains. It feeds on stagnant rotting organic material.
We spotted this drone fly sipping nectar on a brilliant yellow yarrow (Achillea millefolium). If you look closely, you'll see yellow pollen clinging to its abdomen.
Flies, too, are pollinators!
