In this picture he is scraping a piece of lichen off the side of a tree bark. Prior to this, I had no clue to what lichen is. He gave me a mini crash course. He placed this in his test tube and seeing it was not a big enough sample, he placed it onto the ground. He did not want to take more in order to not cause any harm to the tree.
In this picture he is seen holding a caterpillar. In fact, it is a monarch caterpillar. Great to know seeing before this I was unaware of specific types of caterpillars and what they looked like. After close observation, he gently placed it back under the bush where he found it and it began eating a leaf.
He is observing the bees here. Just watching the every move. he did not capture one for observation. This was plenty to see right here. He just loves insects.
