A stochastic model is proposed for the hunting behaviour of jumping spiders when they are newly emerged from the egg‐sac. The model takes into account the fact that the spiders are often unsuccessful when they attempt to catch prey for the first time and also the fact that their rate of response to prey slows down with time if they are unsuccessful. It is shown that the spiderlings ability to catch perceived prey improves with the number of prey captured. The model has been fitted to experimental data using the method of maximum likelihood and a good fit has been obtained. The model could be used as part of a model for the whole predation system.
