It first landed around 0.5m away from nest's entrance and sat there for a few seconds. It flew a bit closer and waited a similar amount of time. It was gradually getting closer until it finally landed within few inches of the nest's entrance. It entered the nest and reappeared a few seconds later. It entered the nest a couple more times, finally leaving altogether.
It looked like a very big fly (Mallophora perhaps?). Unfotunately I didnt have a camera with me...
It was dark in colour with a bit of white fur at the back end.
Any ideas?
