Web Casting Spiders are nocturnal spiders catch insects much as a fisherman catches fish with a cast net. They spin a web so small that they can pick it up and hold it with their four front legs. A hunting web-caster hangs upside down from its hind legs, the elastic net small and in its […]
We often speak of ticks and mites as if they were two separate groups of arachnids, but ticks are really nothing more than very large, blood-sucking mites that take their meals from reptiles, birds, or mammals. In North America, there are only two families of ticks: the hard ticks, which have the body more or […]
Millipedes don’t attack people and are not dangerous. But if a millipede is handled, the defensive fluid that oozes from its body may irritate the skin.
No, daddy longlegs do not bite people. They are inoffensive creatures that are of some benefit to humans because some species eat insects and because others are scavengers that help to decompose dead organic matter.
The best thing is to do to prevent Chigger bites is to avoid chiggers in the first place. Stay out of the weedy areas in which they are found, but if you must enter such places, you can keep most of them off your body by tucking your pants into your socks and spraying your […]
It is very likely that you have mites living in your skin at this very moment. Most people, about 75 percent of those checked, have minute, almost microscopic, mites living in their hair follicles and sebaceous pores, particularly those of the eyelids, eyebrows, and nose. These mites, which belong to the genus Demodex. seldom do […]
Crab spiders, which do not spin webs, are ambushers that seize their prey when it comes close. Some species wait in ambush on blossoms to catch such nectar seeking insects as bees and butterflies that land on the blossom. A well-camouflaged ambusher is likely to be more successful than a conspicuous one that is easily […]
Some species curl themselves up into tight balls, thus exposing only their armored upper sides to the predator. Many millipedes, but not all of them, have a series of stink glands that open along the sides of the body and that, if the millipede is attacked, emit a fluid or a vapor with an offensive […]
These nocturnal ambushers spend their whole life in a silk-lined burrow in the ground that is covered by a hinged trapdoor made of silk. There they are fairly safe from their own predators but can rush out to seize such insects as grasshoppers, beetles, or ants that pass nearby. Some trapdoor spiders are alerted to […]
All scorpions are predators, and between them they eat an astonishing variety of small animals, most often arthropods such as insects, spiders, millipedes, centipedes, and others. Some of the larger scorpions are known to eat small lizards, snakes, and even rodents. Scorpions are opportunistic predators of small arthropods and insects, and can consume huge amounts […]
