Invertebrates

On Thursday of last week in Biology Lab, our class examined various arthropods, almost all of which were insects. Using microscopes and a key similar to that of a dichotomous key one uses to identify trees, we identified which order each chosen arthropod belonged to. To the naked eye the "bugs" are not the most impressive, interesting, or complex group of organisms. But once we put them under a microscope and looked for characteristics unique to that "bug." We had to examine all the parts of these arthropods that one never notices when passing a flower bed, or swatting a pest. For example, we weren't simply to identify if the creature had wings, but how many, and if those wings were the same or different sizes, and if the wings had many veins. We were also called to examine the mouth and antennae of the animals, and decide how many segments made up the antennae, and what type of mouth parts the certain arthropod had. The process was even more detailed than what I have mentioned but to describe it all would be very time consuming. This lab really opened my eyes to how intricate and delicate things are outside of what I observe walking around, taking the time to sit down and analyze these bugs that are often over looked or taken for granted was a great experience.

  1. This was just a thin slice of arthropod biodiversity of Kentucky, which is itself just a small number of global arthropod diversity. Pretty astounding!
