Ferocious flying insects

Mosquito - Anopheles mosquitoes are the only species known to carry malaria.

Asian giant hornet - Aggressive and fearless, the Asian giant hornet is the honey bee's worst nightmare. But humans have fallen victim to this merciless critter on numerous occasions.

Flea - Fleas suck blood from humans, birds, reptiles, and wild and domestic animals. The rat flea is well known as a vector of bubonic plague and flea-borne typhus.

Tsetse fly - The tsetse is a biological vector of trypanosomes, which causes human sleeping sickness and animal trypanosomiasis.

Africanized bee - The original "killer bee," Africanized bees are so named after the East African lowland honey bee, which was introduced to Brazil in 1956.

German yellowjacket - Yellowjacket or yellow jacket is the common name in North America for predatory social wasps. One species stands out, the German yellowjacket.

Tarantula hawk - Tarantula hawks are armed with one of the most painful stings on the planet.

Warrior wasp - A sting from one of these insects results in an intense pain that can last up to 30 minutes.

Western yellowjacket - Though they tend not to sting unless a violent struggle occurs, western yellowjackets nonetheless violently protect their nests and can sting repeatedly.

Tropical carpenter bee - It looks like a beetle on steroids, doesn't it? And indeed, the tropical carpenter bee is a very large and robust insect. However, it's actually a gentle giant.

Yellow fly - Again, it's the female you need to watch out for. She's one of the most serious biting fly pests out there. And she's crafty.

Black fly - A common nuisance for humans, black flies spread several diseases, including the terrible river blindness in Africa.

Red paper wasp - While not the most agonizing sensation on the block, a sting from one of these guys is often painful and causes localized swelling and itchiness.
