![]() If dead, include a cotton ball soaked in rubbing alcohol to preserve it. If alive, include a small piece of paper towel. Or put them in a small container, like a plastic pill vial. ![]() Bring your spiders to the Museum's front desk. Make sure to note where you found the spider. Check daily for spiders and place any spiders in a small container of rubbing alcohol to preserve itįill out the data sheet. Bury a container like a yogurt cup flush with the ground. To collect nocturnal wandering spiders, try a pitfall trap. Use a spoon to stir the material around while looking for spiders. With a trowel, scoop some dirt and leaves onto a pillowcase. To collect spiders from leaf litter, search for piles of leaves, like under bushes or in flowerbeds. Then slide a notecard beneath the spider to trap it. To capture a spider, place a plastic container over the spider. Since many spiders are nocturnal, look at night too. Sometimes you will come across a spider wandering. The longer you spend quietly looking, the more you will find. You just have to look-in bushes and flowers, under rocks, bricks and logs, wrapped in retreats tucked into leaves, in leaf litter, under pots, in crevices, in walls and fences, on window sills. If looking under rocks or logs, lift from the far side so that the object is between you and any creature living underneath. Use caution collecting and do not put your hands anywhere you cannot see. Although the widows are the only spiders in our area which are considered dangerous, all spiders (except one family) have venom and may bite. Without your help, they can't get the full picture. Help our scientists find out which spiders are in L.A. Many people needlessly fear spiders, but most are harmless to humans. Because they are so common, they often come into contact with people, and we receive many telephone calls requesting information about spiders. They exist in vast numbers and are the primary predators of the equally common insects. How to Participate Why Are We Conducting A Survey? The museum cannot be responsible for the treatment of bites or for any injury or illness resulting from the project. If you have any concerns about participating, we suggest you do NOT participate. ![]() Also, we want to know how urbanization and the loss of natural habitat has affected populations and distributions of naturally occurring spiders.ĭisclaimer: The museum appreciates your assistance in this scientific project. We need to know how widespread these introduced species have become, and how they have interacted with the native spiders. As an important international port, new species of spiders from various parts of the world are always being accidentally introduced into the Los Angeles area, and some of these have established breeding populations. There are no truly large collections of urban spiders from this area, as most collectors concentrate on studying natural areas. In spite of their importance and abundance, we do not know much about the spiders in Los Angeles. Want to help? See the 'How to Participate' section below for instructions. We will report our major results on this website. ![]() Spiders collected in the survey will be used to create a database about the distribution and abundance of the species. If requested, we will contact the person submitting the spider with information about its identity. Once the specimens arrive here, our team of experts will identify the specimens, make a collecting record, and place the spiders in the collection. We are asking people to collect spiders in their homes and gardens, fill out a simple data sheet about their collection, and send or bring them to the Natural History Museum. In order to conduct a large-scale survey of urban spiders, we need the help of the public. ![]()
