Spiders, Harvestmen and the Tuning Fork Trick That Teases Them 2026

A spider walk led by Fran Garcia, a member of the British Arachnological Society, turned an ordinary afternoon at an abbey bandstand into a hands-on lesson in arachnids. The group of 10, including two children, learned how to tease spiders out of stonework and brick walls using surprisingly simple tools, including a tuning fork.

The walk began with an introduction to spider anatomy and web building, delivered with lively humour and a bizarre range of props. Wire and ropes of varying thicknesses, a bottle of glue and a folding knife all helped explain how spiders spin silk and how tarantula jaws work.

What Happened on the Spider Walk

Fran passed around an egg sac from a wasp spider, Argiope bruennichi, a species found in southern England but moving north. Teardrop-shaped and papery, the sac was subtly marked in grey and beige to blend with grasses, a reminder of how carefully spiders protect their young.

Then the group set off on a spider hunt. The first stop was the stonework of a small bridge, where the search for harvestmen gave Fran a chance to clear up a common confusion.

Harvestmen Are Not Spiders

While harvestmen are arachnids, they are not spiders. They have eight legs, but they cannot spin webs, have no venom and possess just two eyes rather than eight or six, mounted on a turret.

Spindly legged and loping, they were camouflaged and hard to spot against the stone. That camouflage is part of why so many people walk past them without ever noticing.

Laceweb Spiders in an Old Brick Wall

Nearby, in an old brick wall, the group found laceweb spiders, Amaurobius species, their silken tunnels tucked into pits in the mortar. At the entrance, strands of silk allow a spider to sense vibration from approaching prey.

The children were fascinated to watch as Fran demonstrated how that vibration sense could be triggered, which is where the tuning fork came in.

Why the Tuning Fork Trick Works

Spiders rely on vibration rather than sight to detect prey. By touching a vibrating tuning fork near a web or tunnel entrance, you can mimic the signal of an insect landing, drawing the spider out.

It is a simple, low-tech technique that makes arachnids visible without harming them. For families, it turns a walk into an interactive experiment rather than a lecture.

• Spiders sense prey through vibration, not just sight
• A tuning fork can mimic an insect landing on a web
• Harvestmen are arachnids but not spiders
• Laceweb spiders hide in mortar pits and silk tunnels
• Wasp spiders are spreading north in England

What This Means for Nature Lovers

The walk shows how much can be learned in an ordinary churchyard or park. Old walls, bridges and stonework are habitats, and the species living there are easy to overlook.

For grandparents and parents, it is also a practical way to get children engaged with nature. A tuning fork and a curious eye may be all you need.

Experts like Fran Garcia play a key role in this kind of public education. By explaining anatomy and web building with props and humour, they make arachnids less frightening and more fascinating.

What to Watch Next

As wasp spiders continue moving north, sightings may become more common in gardens and parks. Recording what you see can help researchers track these shifts.

The same theme surfaces in Indonesia's Toxic Haze Crisis: Families Battle Wildfire Smoke, which takes a different angle.

Local spider walks and nature groups are a good starting point. They offer expert guidance and a chance to handle specimens safely. Context on how this played out before sits in Stroke Rehab Crisis: Only 6.4% Get Recommended Therapy.
