It's a bug-eat-bug world out there.
Today we watched a syrphid fly, aka "hover fly" and "flower fly," circling a blanket flower (Gaillardia) and then touching down to sip a little nectar.
Syrphids are called "hover flies" for good reason. They "hover" over a blossom, helicoperlike. They're often mistaken for bees but to the trained eye, they really look nothing alike. Folks confuse them because both bees and syrphids are floral visitors and both are pollinators.
If it's a floral visitor, it must be a bee, right? Wrong.
Anyway, this syrphid touched down on the blossom to sip nectar, its wings glinting in the early morning sun. Finally, it spotted the danger, a jumping spider lurking on the other side. The crafty predator lunged. Missed!
When we returned a few minutes later, however, we saw the jumping spider beneath the petals, feasting on the syrphid.
Quickness is an attribute--whether you're a jumping spider or a syrphid.
