Animal Crossing New Horizons Blathers bug and insect phobia

In Animal Crossing New Horizons A resident  has appeared to the island called Blathers, he is a insect and fossil fanatic and a professor and he opened a museum including fish, fossils, insects, but there is 1 problem , and that is that he hates insects, and every time you introduce a new bug to him he just shivers and he refuses to assess it, which I find funny and weird because he specialises in those kinds of things.
