Why we love them

The common harvestman is a gentle little creature with a tiny round body and eight very long, thread-thin legs. People often call it a “daddy longlegs.” It may look like a spider, but it is not a true spider at all. A spider’s body has two parts joined by a narrow waist, while a harvestman’s body is a single little bead, with all those wonderful legs sprouting from it.

Here is something reassuring: the harvestman has no venom whatsoever, and it cannot spin silk, so it never makes a web. It has no way to harm anyone, and there is nothing to fear from it. If it feels worried, it simply tiptoes away on those long legs, or stays very still and hopes not to be noticed. It is one of the gentlest of all the eight-legged animals.

Those famous long legs are more than just for walking. The second pair are the longest and work a little like feelers, tapping the ground ahead to sense the world, since the harvestman cannot see very well. It picks its way carefully over leaves and stones, and if a leg is ever lost, it can carry on quite happily walking on the ones it has left.

The harvestman is a helpful little recycler. It wanders about nibbling tiny soft insects like aphids and caterpillars, and it also cleans up bits of dead plants and animals it finds along the way. By tidying away this leftover material and eating garden pests, it does a quiet, useful job in gardens, fields, and farmland.

The common harvestman is the most widespread harvestman in the whole world. It lives naturally across Europe and Asia and has spread to North America, North Africa, and New Zealand, turning up in grassy places, hedgerows, and gardens. It has not been listed as needing special protection. Wherever it goes, this long-legged, harmless helper quietly gets on with tidying up the world.

A harvestman is not a true spider — it has one round body instead of two parts joined by a waist, and it makes no silk and no web.

It has no venom at all and is completely harmless to people.

It is a gentle recycler, eating tiny bugs like aphids and caterpillars and nibbling bits of dead plants and animals to help tidy up.

Every common harvestman can feel happy, scared and loved — just like you.
