Monarchs Week 5

This week was truly monarch mania and had all of us here in Cape May glued to the skies swirling with black and orange splendor.  Even the birders couldn't ignore the plethora of plexipus!  The census has reflected this influx of monarchs with a whopping 210.0 dpph (Danaus plexippus per hour).   I must also note that last week's dpph has changed due to a calculation error, which has now been corrected. Here is the updated graph:

PSSSSSSSST!!!--- If you are looking for Monarchs roosting, check out the pines along the dunes of Lincoln & Cape Ave.  Also, tonight  I found several small roosts of monarchs in Cape May Point State Park along the trail by the dune. Look for them in the bayberry there.

Keep your eyes on the skies (and in the bushes)!

  1. Hi,
    My name is Anna Lisa Diaz and I am currently the monarch biologist down at the Coastal Virginia Wildlife Observatory in Cape Charles, VA. While tagging butterflies yesterday, I came across a tagged one- PBH207. I was just curious if this happened to have been tagged from you guys and when you tagged him.

    Much appreciated!

  2. Hi Anna! I am so glad that you contacted us! I don't know if anyone has responded to you, but I don't believe that is one of our tags. Thank you for asking though! Please keep in touch if you see any more tags or have questions! You can contact us here at
