A Rhinocerous in our BACKYARD!

Ok, so my title is slightly misleading, but still -- check out this awesome beetle we found outside! You know the bug is big when you can HEAR it crawling around under the leaf litter:



What a great find! If you were wondering, it's a beetle in the dynastinae family, a rhinoceros beetle. Just check out that horn, if you've found a cooler beetle, I want to see it.

If you're on the hunt for a beginner's field guide to identify the creepy-crawlies, I highly recommend you check out the Peterson's First Guide collection. I think we've checked most of them out of the library and the insect and bird ones will make an appearance under the Christmas tree this year. I find these guides are great for an intro to taxonomy without being too bulky and overwhelming for little hands (and at $6.95 I won't cry for too long if they're lost).



Claire loves to watch the bugs do their work, the insect world is certainly a fascinating place. I loved her reaction when we tipped over a log and found a nest underneath with oodles of ants running around. Check out her estimation skills below, judging by her confidence in the number, I'm sure there are exactly 88 ants. Heehee!

Tadpole Observation (A Cautionary Tale)


In early spring the frogs gathered by the hundreds in our small pond and spent a very noisy weekend engaging in...well, you know. Think Woodstock, 1970s, lots of free love and partner swapping. Egg upon egg upon egg was floating in the water. It was so remarkable I had to photograph it. See an earlier post here.

Really, it was a bit ridiculous.

I swiped a few eggs for observation and we watched tiny tadpoles hatch and devour algae and leaf litter in a tank set up in the office. We'd keep them for a few days then dump them back in the pond to experience bigger digs. Rinse and repeat. We're on the fourth or fifth tadpole infusion here.

Except this time, I scooped something else up too. Leeches. A lot of leeches.

We've seen a few tadpoles in the pond with a leech attached to them, but they seemed just fine. The leech would glean a blood meal and off they'd go, right? All knowing Google told me the leeches in my pond primarily ate the detritus in the muck at the bottom.

Google was very wrong.

Last night we noticed a tadpole in the tank had a leech on it. And then 2 and then 4...and I didn't want to try and remove them because I thought detaching them might injure the poor guy more.

Checked on the little guy this morning and there is nothing left of him but some translucent skin and a dark green little mouth. Looks like they saved the lips for last. Ugh. Shiver me timbers.
