What is a fairy, generally? It is a tiny, Tinkerbelle humanoid with magic living in a forest. Insects are mostly a nuisance to humans, but if you're a little itty bitty fairy wouldn't those be fucking terrifying?
An insect, one as big as you are, is living nightmare fuel wearing armor. Also, fairy don't like "icky things". Bug should've been super effective and/or resistant to Fairy all along.
