Bird migration was intense over Pittsburgh on Friday night, 4 October, when more than 20,000 songbirds flew south overhead. We saw the results on Saturday morning in Frick Park where a new cohort of species had arrived with good news: Some of them were eating spotted lanternflies!
The new species included ruby-crowned kinglets, white-throated sparrows, yellow-bellied sapsuckers and yellow-rumped (myrtle) warblers. The mix was quite a change from September’s warblers.
Most of the new arrivals were feeding on tiny insects but the juvenile sapsucker, pictured above, was attracted to sweet lanternfly honeydew on ailanthus trees. He was too young to have ever seen a spotted lanternfly but he was curious. “Are these edible?”
Yes.
Perhaps the sapsucker got the idea from a northern cardinal that ate a lanternfly further down the trail. (I don’t have a photo of that incident; this one is from iNaturalist, New York.)

Olive-sided flycatchers eat spotted lanternflies, too, though they don’t contribute much because they are rare in Pittsburgh.
However, when an olive-sided flycatcher was passing through Howard County, Maryland in early September Mei Shyong photographed it eating a spotted lanternfly. The thumbnail below is just a hint. Click here or on the image to see her photo at Howard County Concervancy on Facebook.
