A spider eating a fly is not a pretty sight. The insect is first bitten by the spider, which then wraps it in its silk. It then waits until the fly is dead before eating it. When the fly dies, the spider vomits its digestive fluid over it, liquefying the fly into pulp.

Web building spiders
Web-building spiders live in uninhabited areas and use their webs to catch fly and other insects. They have excellent eyesight and are agile. They have modified padded feet and strong legs. These attributes enable them to climb walls and run quickly to catch their prey.
Jumping spiders
Jumping spiders are easy to care for and they are generally not picky eaters. Moreover, they do not bite humans! You may even find them cute!
Yellow garden spider
This brightly colored garden spider is a good friend for gardeners, as it eats a wide variety of insects. The spiders use their long, fused head and thorax to detect prey and can kill insects that are detrimental to the health of your garden, including aphids and beneficial insects. The spiders also serve as deterrents for flying pests, preventing their resurgence.
Long-legged cellar spider
Long-legged cellar spiders do not bite humans. Although they have a reputation for eating flies, this spider is not considered dangerous. Their fangs are too short to penetrate human skin during a bite. However, this does not prevent them from invading other spider’s webs and devouring their prey.
Robber flies
The Robber Fly family of flies are not known to bite humans. Their larvae overwinter in the soil, pupate and emerge as adults. These flies live from one to three years. During warmer months, larval development is accelerated. Adult robber flies are cosmopolitan and can be found all over the world. However, they are not found in the Antarctic.
Baby jumping spiders
Baby jumping spiders are born in the nest of their mother, but they leave the nest at about 20 days old. Until 40 days, the spiderlings feed on the mother’s milk. This extended feeding period helps the young survive. When you buy jumping spiders, it is best to avoid cutting them off their milk too early.
Captive jumping spiders
Jumping spiders are very colorful creatures with eight pairs of eyes. They are usually fuzzy and the males can have bands of jewel tones on their bodies. Unlike other spiders, jumping spiders do not build webs and instead track their prey on foot. Their great vision allows them to strike their prey from great heights.
Mealworms
The darkling beetle feeds on mealworms, the larvae of which are often stored in grains and flour. The mealworms are very nutritious and are used in animal feed, bait, and research. Spiders have also been known to feed on these worms. If you suspect your spider is eating them, the best way to prevent it is to offer them a safe source of food.
Crickets
Crickets are omnivorous insects, which means they eat both meat and plants. They are most often found in yards, barns, and basements. They are often a nuisance in agricultural settings because they consume crops.
Mosquitoes
Spider eating flies are insects that feed on spiders. They are called Small Headed flies and they develop inside spiders and then attack them. The fly tries to kill the spider, but in the end, they just eat it.
