Do insects think?
Yes, if you define thinking as making choices and having memories. Their brains are not the same as ours, but that does not mean they are not capable of thought and learning. Bees can remember and learn, for example. They make choices based on the past experiences. Ants have a sophisticated system of navigation in which they uses a variety of cues, both visual and chemical. A researcher in my school studies be behaviour and intelligence, and his findings are rather astounding! They are even capable of higher order thinking.
