Feelers out - what's about? Join Jess and her friends as they go on a harvestman adventure. In her treehouse den, Jess is looking at harvestmen - many people think of them as daddy long legs. Jess explains that they look like tall spiders but harvestmen are actually quite a different creature. Setting off on a minibeast adventure, she meets up with some children and searches for harvestmen with them. They discover that they are not at all frightening and are, in fact, very interesting. For a start they have a very large number of knees. Then they compare a harvestman with a spider and see how it is very different.
