Sometime in the '60s I read a story which was the first person account of an expedition sent to explore earth which failed because the aliens were the size of ladybirds. It sounds a bit like Nicholas Fisks' "The Boy, the Dog and the Spaceship" in Edmund Blishen's Science Fiction Stories, but was definitely written at least in part in the first person from the point of view of the alien. It was rather poignant as the expedition started out in great excitement and anticipation only to end in the casual destruction of the spaceship and all its crew. Any ideas?
In this story, the aliens arrive in a spaceship that resembles a wasps' nest in structure and people just imagine that they are insects. The narrator is one of the aliens and writes quite poignantly of the death of their home planet and of his excitement at being picked as part of the exploratory party to the most beautiful blue and white planet. They have what they think are devastating personal defence weapons, but when humans pick them up, they simply think they have been stung.
