This is a Horsetails, it is in the same category as a fern. They reproduces by using spores and are vascular. It also does not not flower. These plants were thriving during the Paleozoic era.
Three creeks park in floodplain. Common in patches
Garlic mustard just starting to flower
One of two seen below the observation deck near the Audubon Center.
Very Common around campus.
Half the size of E. Gray Squirrels, reddish dorsal coloration and tail. Not uncommon to find in the woods along the river in this area.
Regularly found in the experimental ponds. Tail was round (in cross-section) and not flat, ruling out beaver.
Location: Haul Rd quarry ponds
QUESTION MARK or EASTERN COMMA.
It was seen flying around the canopy of a large elm just outside my office window on the OSU campus. Viewed with bionculars, the wing shape and upperwing and underwing coloration suggested Eastern Comma or Questionmark, although I didn't see it well enough to rule out one or the other.
Seen about 5 feet above the ground, clinging to the south east side of the Aranoff Lab building on The Ohio State University main campus in Columbus, OH.
Window-collision mortality near the main entrance of the Ohio Historical Society.
I was at the park working on my paper, while my car was charging. I saw this white squirrel running around! He sure doesn't blend in well.
Sorry about the poor picture quality, I only had my phone.
