Abstract Lenz:

In this work, we look at the flight statistics of foraging bumblebees and its changes due to the presence of different kinds of artificial spiders. We are analysing the velocity distributions of the bumblebee flights given data from an experiment done by Tom Ings and Lars Chittka. Via Quantile-Quantile-plots we find that the distributions differ in the tails under varying environmental conditions and also for the different directions of the flights. With a Maximum-Likelihood-Estimate we try to find the likeliest shape of the distribution at the tails and look at the importance of the choice of the cutoff value for the estimation.
