Today I co-led a hike with Bill Walker and Chuck Holliday at Wetlands West Park in Liberty Township. We had a nice turnout and it wasn't too hot - temps in the low 80s. To prepare for the hike, I spent last week reading about the subjects. Ralph and I actually walked around the pond last Saturday so I could see for myself what was there. We saw bullfrogs and greenfrogs. The bullfrogs are larger, 4-8 inches body length (not counting their legs) and green frogs are 2- 4 inches in length. Bullfrogs have large mouths and can swallow birds, chipmunks, fish, insects and other frogs. They are native to the eastern U.S., but have been introduced to Texas and California and are now considered invasive species - eating up all the native frogs and insects. Last week we saw a mallard grab a green frog and swallow it whole. Ralph managed to get a picture.
Today on the hike we saw some interesting dragonflies and damselflies. Damselflies are not female dragonflies, like I thought. They are a separate group. They are smaller than dragonflies and when perching, they fold their wings together, whereas dragonflies, at rest, keep their two sets of wings spread out like an airplane. The prettiest dragonfly we saw (in my opinion) was the common whitetail. These guys fly so fast, up to 30 mph, that I couldn't get a picture. But I obtained some stock pictures off the internet.

The dragonfly reproductive cycle is interesting. The female dragonfly will dip her tail (abdomen) in the water and lay eggs. In a few days they hatch into nynphs.

Nymphs eat mosquito larva and other insects and live in the water about a year. They are about an inch long and their abdomen is divided into shelf like segments. When the time is right they crawl out of the water, shed their shell, and become dragonflies.
Another pretty dragonfly we saw today was the widow skimmer. This insect has saddlebag-like black sections on its body near its abdomen.

We also saw a blue dasher at rest.

Chuck brought his nets and managed to catch this blue dasher dragonfly, which we later released.
