Is it on a web out in the open? Some brown web-building spiders that are not brown recluses. Clockwise from top left: If you find a brown spider on a web out in the open, it is not a brown recluse.
Unlike the various brown web-building spiders shown above, each with their different types of web, brown recluse spiders do not use silk for prey capture. They do build small irregular silk retreats in which they hide during the day. These retreats are made low to the ground and out of sight in cracks and crevices or under objects like rocks. I should mention that house spiders in the family Agelenidae are probably the most likely spiders to be mistaken for brown recluses in Canada.
While females will usually be found on their webs, males are often found out and about when searching for females. These spiders are often mistaken for recluses, but note the pattern on the abdomen.
If you find a spider that has stripes or large spines on its legs, it is not a brown recluse. Brown recluses have plain brown abdomens and plain brown legs with fine hair but no large spines.
Does it have extremely long and skinny legs? Cellar spider, Pholcus phalangiodes family Pholcidae. This is not a brown recluse. Sean McCann If it has extremely long skinny legs like the spider in the image above, it is a cellar spider or daddy-longlegsnot a brown recluse.
Having a violin-shaped marking is not, by itself, a good way to determine if a spider is a brown recluse. Is it really big? Brown recluses are not huge spiders. If its body length not including legs is more than 0. Does it have 8 eyes?
This is the dead giveaway, provided you are close enough to the spider to count its eyes. Below are some 8-eyed spiders that are sometimes mistaken for brown recluses. A wolf spider family Lycosidae. It looks a bit like a brown recluse, but again, has 8 eyes, some larger spines on the legs, and a dark stripe on the abdomen.
Huntsman spider family Sparassidae. These spiders are fairly frequently mistaken for brown recluses. Note the 8 eyes in 2 rows, and spines and darker dots on the legs and abdomen. The 8 eyes are all tightly clumped together, it has conspicuous spines on the legs, and its pedipalps the two small leg-like appendages at the very front end of the spider are extremely long and stick straight out in front of its face compare to a male brown recluse spider here.
Male southern house spider Kukulcania hibernalis. It is a well-known epiphytic plant that grows on the branches or trunks of other trees. Orchids are usually found in dense tropical forests.
They form their base of attachment on the branches of trees, and benefit by getting adequate sunlight and nutrition that flows down the branches. The orchids do not grow to a large size, and thus the host tree is not harmed in any way.
Remora Fish and Sharks The remora, also called suckerfish, belongs to a family of ray-finned fish. It is a small fish growing up to a size of 1 to 3 feet. The remora forms a special relationship with sharks and other sea organisms like whales and turtles.
It has special suckers attached to its fins. It attaches itself to the bodies of sharks, and uses the shark for transportation as well as protection from its predators. It also eats up the scraps of food that are left over when the shark eats its prey. Pseudoscorpions and Beetles Pseudoscorpions are scorpion-like insects that usually grow to less than one centimeter in length.

They are different from other types of scorpions in the way that they do not have stingers. Some species of the pseudoscorpions hide themselves under the wing covers of large insects like beetles.
This gives them protection from their predators, and also provides them a means of transportation over a larger area. Because of its small size and lack of sting, it does not harm the beetle in any way. Monarch Butterfly and Milkweed The Monarch butterfly is a well-known type of butterfly found commonly in the North American region.
Examples of Commensalism for a Better Understanding of the Concept
At the larval stage, it forms a commensal relationship with certain species of milkweeds. The milkweeds contain a poisonous chemical known as cardiac glycoside, which is harmful to almost all vertebrates. The Monarch stores these poisonous chemicals in its body throughout its lifespan. When a bird eats a Monarch butterfly, it finds it distasteful, and gets sick. Thus, they avoid eating it. Birds Following Army Ants Many birds form a commensal relationship with some species of ants like the army ants.
A great number of army ants trail on the forest floor, and while moving, stir up many insects lying in their path.
The birds follow these army ants and eat up the insects that try to escape from them. The birds benefit by catching their prey easily, while the army ants are totally unaffected.

Burdock Seeds on the Fur of Passing Animals Many plant species have adapted themselves by developing curved spines on their seeds or seedpods in order to disperse them over a larger area. The burdocks are a common type of weed that are mostly found along roadsides, and on barren land and fields.
The burdock seeds have long, curved spines attached to them.
