On the front they have two small "mini-legs" called palps. These are used to grab prey, and in mating, and are much bigger in male spiders than in females. All spiders have fangs that they use to bite their prey with, like most spiders, jumping spiders have venom glands that produce toxic chemicals that help paralyze and digest their food. This is the largest family of spiders, with over 5, species around the world.
These spiders roam in a wide variety of habitats. Pretty much anywhere they can find prey, they will live. Like all spiders, Jumping Spiders hatch from eggs, and the hatchlings are very similar to the adults, only smaller. As they grow they have to shed their skin all at once, this is called molting. Most Jumping Spiders have to molt 5 or 6 times before they become adults. Most Jumping Spiders don't live for more than about a year, but some species may live longer, especially in cold climates where they have to be dormant for many months each year.
Because they rely on their vision to hunt and find mates, these spiders are mostly active during the day. At night, and when molting, they hide in small chambers made of silk and attached to vegetation. Some species in this group have courtship dances. The males are brightly colored, and they wave their front legs and dance to communicate to a female.
Jumping spiders will also eat worms they can find around them, including wax worms and meal worms. The spider will take the opportunity when the worm comes out and pounce on it. Sometimes, the spider will create burrows and holes just to catch these worms. This acts as a surprise for the worms, as the jumping spider creates an opportunity for itself to catch the worms and have a good meal.
There is a body of research that points towards a fascinating occurrence: small jumping spiders preying on animals that are up to three times larger than them.
Small jumping spiders — regal jumping spiders, in particular, have the ability to catch animals that are two or three times larger than them, according to research. Regal jumping spiders are one of the larger species of jumping spiders, as they can reach a size of about an inch. Still, it is a great achievement for the jumping spider to prey on frogs or lizards that are several times larger.
The most important mechanism that allows them to do so is their jumping ability. Some jumping spiders will use their venom to kill or paralyze the larger animal. Yes, jumping spiders will also eat ants as a snack. Occasionally, the jumping spider will eat ants as a smaller meal if they can find ants. Jumping spiders will sometimes eat other spiders that are smaller than them in size.
They will still prioritize insects and other animals they can catch, although occasionally, they will also go after smaller spiders. Jumping spiders are carnivores, which means they eat meat-based sources primarily. However, they might suck the fruit nectar if they find an opportunity to do that. Jumping spiders are one of the most fascinating spider species in the world.
They depend much upon their sense of sight to hunt or to court. It is apparently for this reason that many jumping spiders have iridescent markings or colors on their bodies, legs and chelicerae.
Some dermatologists believe jumping spiders are the most common biting spider in the United States. Persons gardening are said to be at risk for disturbing the habitat of this spider which may react by jumping on exposed skin and inflicting a bite. The bite is usually asymptomatic to slightly painful and subsequently results in a local reaction such as an erythematous papule or a small urticarial wheal.
