So sorry for being late all over again... real life got very busy these last days and on top of that I was really struggling to find a picture of something small.
So, in the end, I'm going with this horse fly I came across outside the Clearwell Caves. It's not exactly small, in fact it was enormous!!! O_O At least 6-7 cm long, very scary. Made a sound like a whole bee swarm. But in comparison I suppose it's still small, even when it scared me to death when it flew directly at me. *brrr*
