Yes, the "daddy longlegs" that flies is the Crane Fly (Tipulidae), a harmless insect with wings, while the non-flying types known by the same name are Harvestmen (Opiliones) and Cellar Spiders (Pholcidae), both arachnids without wings, so they can't fly. The confusion comes from the common name being used for three different creatures, but only the flying insect (crane fly) fits the description of something that flies with long legs.
Yes, it's generally a good idea to leave daddy long legs (also known as harvestmen) alone. They are harmless creatures that help control pest populations by feeding on small insects and decaying organic matter. They don't bite humans and are not aggressive.
The common name “daddy long legs” creates endless confusion because it's used for three different creatures. In our DMV area, homeowners typically use this name for both cellar spiders and harvestmen. Additionally, some people call crane flies by this name too.
In colloquial speech, crane flies are known as mosquito hawks or "skeeter-eaters", though they do not actually prey on adult mosquitos or other insects. They are also sometimes called "daddy longlegs", a name which is also used for arachnids of the family Pholcidae and the order Opiliones.
Crane flies are found throughout Australia.
Crane flies might look big and scary and can destroy your lawn, but they are medically harmless to people. With good lawn care, you can get rid of most crane flies.
The Lord Howe Island Phasmid or Land Lobster, Dryococelus australis, may be the rarest insect in the world and is possibly also the rarest invertebrate. Once abundant on Lord Howe Island, it was thought to have been extinct after a shipwreck introduced rats to the island in 1918.
The daddy longlegs is actually a large type of cranefly, of which there are 94 species in the UK. It is familiar to us in its adult form as the gangly insect that flits around our homes in summer. As a larva, it is a grey grub (also known as a 'leatherjacket') that lives underground, feeding on plants stems and roots.
It can be irritating when flies come buzzing into your home, but you should avoid killing them if at all possible, experts have said.
Deer flies: usually smaller than horse flies; often have spotted eyes and a dark-spotted pattern on the wings. Horse flies: usually larger than deer flies; usually have solid or striped eyes.
daddy longlegs cause no harm to structures or to the people inhabiting them. Unfortunately, some people fear daddy longlegs because they've heard myths about them being poisonous. However, this is untrue.
You shouldn't squish a wolf spider because they are harmless pest controllers, and squishing a female releases hundreds of babies, potentially increasing a spider problem in your home rather than solving it, as the spiderlings scatter into crevices to survive. These beneficial spiders eat other pests like roaches, ants, and mosquitoes, and squishing them can be counterproductive and spread harmful digestive enzymes if they burst.
The Sydney funnel-web spider (Atrax robustus) is widely considered the world's most dangerous spider due to its highly toxic venom, large fangs that pierce skin easily, and aggressive nature, with the male's venom capable of causing death in humans before antivenom (introduced in 1981). While other spiders like Brazilian wandering spiders also have potent venom, the Sydney funnel-web's combination of toxicity and propensity for biting humans, particularly in populated areas, earns it the top spot for danger.
Spiders hate strong, pungent smells, especially essential oils like peppermint, tea tree, and lavender, as well as scents from citrus (lemon, orange), cinnamon, eucalyptus, and cedar, which disrupt their senses. You can deter them with DIY sprays using these oils mixed with water, or use plants like basil and marigolds, or even vinegar, though vinegar's effect is temporary.
While the theory is unproven, it is likely that spiders can detect human fear.
99% of spiders lack the capacity to form meaningful bonds like we humans do, so the feeling won't be mutual.
Mosquito
The deadliest insect is, in fact, the deadliest critter in the entire animal kingdom. It is the humble mosquito, which kills more than 700,000 people every year. Skeeters are vectors for a host of nasty diseases, including malaria, dengue, West Nile, yellow fever, Zika, chikungunya, and lymphatic filariasis.
Several factors can contribute to a sudden increase in flies in your home: Decaying organic matter: Flies are attracted to rotting food, garbage, and other decomposing materials. These substances serve as ideal breeding grounds, quickly leading to infestations.
The next time you come across ants, cockroaches, spiders, houseflies, or other insects, don't swat them—remember they feel pain, and treat them humanely instead. Bugs and other animals are like you, only different!
They're the Good Guys. You may not like them, but harvestmen are actually helping you out. Daddy long legs eat spiders, earthworms and other insects. They'll also scavenge for dead insects, decaying plant material and insect eggs if live prey isn't available.
And if you inspect closely, spiders have three or four pairs of eyes whereas grandaddy longlegs only have a single pair. These eyes are rather primitive and are only thought to discern light and dark and pick up movement.
Daddy longlegs, also known as harvestmen, sometimes exhibit a bobbing or vibrating behavior, often described as a "dance," as a defense mechanism against predators. This behavior can make it more difficult for predators to target them accurately or may even deter predators due to the unusual appearance.
The hardest pests to get rid of are generally bed bugs, cockroaches, and termites, due to their resilience, rapid reproduction, and ability to hide in tiny, inaccessible spots, often requiring professional intervention and specialized methods like heat treatment or advanced baits. Rodents (rats/mice) and ants are also extremely challenging because of their intelligence, prolific breeding, and complex colony structures.
The insect assassin
The assassin bug isn't just a character from a horror movie; it's a real-life creepy bug that hunts down other insects. It has a powerful, needle-like proboscis that allows it to inject venom into its prey, liquefying its insides before sucking it dry.
