Get to know your eight-legged lodgers this autumn

They are useful pest controllers and like to share our homes, but many of us cannot identify different species of these eight-legged lodgers.

Spiders start to appear in our houses more frequently at this time of year, as some species – including the aptly-named House Spider (Tegenaria) – leave their webs in search of a mate.

Is there an identification guide your society needs?

There are many wildlife identification guides or keys that either haven’t been written yet or would benefit from an update. OPAL is collecting opinions from natural history societies on what guides need to be produced.

It could be a guide aimed specifically at beginners or advanced users. We’ve already received a number of suggestions, including sawflies, soldier beetles and adult caddisflies.
