Frog Pond Study Plus a Rattlesnake Friend
Our first attempt at a tadpole/frog study was unsuccessful. We visited my dad's pond and could not scoop up any tadpoles but we did get some great insect larvae to observe in the pond water sample. We brought them home in a bucket and used our pond field guide to try to identify them.
Edit to add: I was told this is not a Mayfly but a Damselfly so I will be off to do some more research....now you will understand why I say I should take Eva's free entomology course down below. :)
Meet the Mayfly....which we learned are called naiads during their aquatic stage. (This is an image of a dead one I found lodged in my net.) They live in ponds, lakes, or streams for up to several years. They molt 20-30 times during that period of time. The most interesting thing about Mayflies is their short lifespan for adults- only a few hours to a few days, depending on the species. We actually observed an adult Mayfly that landed on my dad's shirt while we were observing the pond. What a great insect to learn about!
Even if we didn't find any frogs on this outing, we sure enjoyed our time just being outdoors at the pond.
As a sidenote: I think we need to take Eva's Introduction to Entomology course that she is offering on her blog Academia Celestia. It is a free six week online course in a subject she is highly knowledgeable in and is passionate about. If your family is looking for a way to learn more about insects...click over and see it this would work for you.
We took a second trip to the local walking trail where I had observed some frog's eggs earlier this month. Success! There were hundreds of tadpoles but I didn't get a single decent image...the one below is the best I was able to get with all the reflections but if you look closely you will see some dark tadpoles swimming in the water.
We will continue to observe these critters in the weeks to come...easy to do since they are on the side of our usual route on the walking trail.
I highly recommend this Golden Guide to Pond Life. We have always been able to identify any creatures or plants we found at Grandpa's pond using this simple field guide. Great beginning guide for young ones!

Rattlesnake Video on YouTube....
My husband and I took a hike to the river on a glorious day last weekend. The grass was green, the wildflowers were amazing, and the sun was warm....perfect day for a spring walk through the Northern California foothills.
I was sort of worried about the possibility of encountering snakes but we were keeping a close eye out. I had stopped a few feet off the trail to look at some metallic insects on a wildflower stem. I was trying to get a really close look and then I stepped backwards to the trail. My husband immediately started yelling that he saw a snake....startling me and making me scream. The snake was right by my feet....a really big rattlesnake!
He pulled me out of the way and the snake moved across the trail over to the other side. I (of course) pulled out my camera and started taking a video. That is what you see in the video above....me still all shaky and out of breath capturing this huge old rattler as it slithers into the tall grasses but not without showing us his extremely long rattle.
We ended up seeing three snakes that day, one rattlesnake and two gopher snakes. Just in time for reptile month!
So have you seen any reptiles in your area yet?
