Which type of relationship is formed when a Pseudoscorpion is dispersed by a harlequin beetle?

Explanation: Commensalism refers to a type of biotic relationship in which one of the interacting species is no gain-nor loss condition while the other species is benefitted. Harlequin beetles reside in the dead fig tree. They have the ability to fly.

What is a Pseudoscorpion bug?

Pseudoscorpions are arachnids and are related to spiders, ticks, mites and scorpions. They have oval or teardrop shaped, flattened bodies with two conspicuous pedipalps (pincers). They are reddish or brown.

What is the difference between a scorpion and a Pseudoscorpion?

Like scorpions, pseudoscorpions have a segmented body and two enormous pincers. But pseudoscorpions lack the curved stinger that all true scorpions have. Pseudoscorpions usually live outside in mulch, under tree bark, and in leaf litter. Pseudoscorpions don’t bite or sting humans, and they can even be helpful.

What do scorpions and pseudoscorpions have in common?

Like all arachnids, both pseudoscorpions and scorpions have eight legs each, and chelicerae, exoskeletons and pedipalps. Unlike most other arachnids, though, scorpions and pseudoscorpions have enlarged pedipalps formed as pincers.

What is an example of a Commensalistic relationship?

Commensalism is a type of symbiotic relationship in which one species benefits, while the other species is neither harmed nor helped. An example is a golden jackal (the commensal) following a tiger (the host) to feed on leftovers from its kills.

Do pseudoscorpions eat bed bugs?

Pseudoscorpions often travel by gripping the leg of a fly, beetle, moth or other bug and hitching a ride. This is called phoresy in entomology. The house pseudoscorpion (Chelifer cancroides) is fond of carpet beetle larvae, clothes moth larvae, booklice, and just loves to eat bedbugs.

Are pseudoscorpions rare?

But it’s very rare in other groups of invertebrates. However in 2005 scientists in Brazil found one pseudoscorpion – a miniature member of the arachnid group that includes spiders – was unusually social. A colony contains as many as 175 pseudoscorpions.

Are Pseudoscorpions rare?

How are pseudoscorpions and beetles have a commensalistic relationship?

Beetles and Pseudoscorpions have a commensalistic relationship where the pseudoscor- pions benefit and the beetles are unaffected. Let P represent the population of pseu- doscorpions and B represent the population of beetles.

How does A pseudoscorpion get its free ride?

But a free ride is by no means all that pseudoscorpions get from their beetle host. In flight, they use the beetles as a mobile the beetle’s abdomen. (Cordylochernes scorpioides). They discovered that as harlequin beetles Ecology and Sociobiology, vol 30, p 135). ‘Both males and females compete to board the beetles,’ say the researchers.

What kind of insects do pseudoscorpions prey on?

Pseudoscorpions are generally beneficial to humans since they prey on clothes moth larvae, carpet beetle larvae, booklice, ants, mites, and small flies. They are tiny, and are rarely noticed due to their small size, despite being common in many environments.

How are pseudoscorpions dispersed over a wide area?

A few species of pseudoscorpions disperse by concealing themselves under the wing covers (elyatra) of large beetles such as the cerambycid beetle. The pseudoscorpions gain the advantage of being dispersed over wide areas while simultaneously being protected from predators.
