Harvestmen are arachnids and, as such, are related to spiders and scorpions. They are predators, eating smaller invertebrates which they catch using hooks at the ends of their legs. Harvestmen can be found in leaf litter, amongst foliage and in grass in many habitats. They also often come into houses.

How to Identify

As a group, harvestmen are easy to identify: they have eight very long, spindly legs and a small, round body without a ‘waist’.

Where to Find

Widespread.

How people can help

You can encourage minibeasts into your garden by providing logs, stone piles and compost heaps for them to hide, feed and breed in, along with flowers and nettle patches. In turn, other species will be attracted to the garden, as minibeasts are a food source for many animals, including mammals, birds and amphibians, providing a vital link in the food chain. To find out more about encouraging wildlife into your garden, visit our Wild About Gardens website: a joint initiative with the RHS, there’s plenty of facts and tips to get you started.

Did you know?

Unlike spiders, harvestmen don’t spin silk and don’t produce venom.
