All across western Pennsylvania a wide variety of milkweed is blooming and with it come the insects who depend it, especially monarch butterflies.
Look closely at the underside of milkweed leaves. If you find a small white dot it’s a monarch butterfly egg.
The plant I found didn’t have monarch eggs, but here’s a photo from Wikimedia Commons that shows you what to look for.
I hope the milkweed leaves in Schenley Park have eggs soon …
