From the Society of Biology: There are about 660 different species of spider in the UK, and most of them will never come inside. Each autumn, however, male house spiders come indoors in search of a mate.
This year we are going to record house spiders as they move indoors, and we need sightings from around the UK. A free house spider recording app ‘Spider in da house’ is available through the Android and Apple app stores. The app, developed by us and built by TouchApp, allows people to report their sightings of Tegenaria spiders and helps identify other spider species. Alternatively, you can record sightings online. To subscribe to updates about the survey, please submit your email.
