Ctenizidae (Ctenizidae) build burrows in the ground and cover them with hatches of cobwebs, soil and plant material. They line their tubular burrows with cobwebs. Ctenizids create hinged, hidden doors and when they sense vibration from a passing prey, they pop out, grab their prey, and drag it back down the hole. The diversity of this species makes accurate identification quite difficult, but the steps below will help you determine if you have caught a spider of the cteniside family.

Steps

  1. 1 Find out what ctenizide looks like. Some of its main features are:
    • Physical traits: has a length of 1 to 3 cm.
    • Poisonous: Yes (poison is not dangerous to humans)
    • Habitat: everywhere
    • Diet: These spiders mainly eat terrestrial insects, including crickets, moths, beetles, grasshoppers, and other spiders.

Method 1 of 3: Defining characteristics of cteniside

Ctenisides are black or brown in color. Some species of these spiders have pale markings, while others have a silky coat. Females of ctenisides are larger than males, but you rarely see them as they do not often leave their burrows.


  1. 1 Pay attention to these distinctive features of the male:
    • Short and coarse spinning body
    • Double process, about the middle of the forelegs
    • Dull carapace (carapace is covered in pale golden hairs that give it such a dull appearance)
    • Palps, which look like boxing gloves
    • Two close rows of eyes. Four eyes in each row. Some varieties have a distinctive three rows of eyes.

Method 2 of 3: Cteniside Habits

The geographic distribution of ctenisides is chaotic, which can be associated with continental drift. Various types of ctenisides can be found all over the world.

  1. 1 The habitat of ctenisides can be called:
    • USA (southeastern and pacific states)
    • Guatemala
    • Mexico
    • China
    • Thailand
    • Canada
    • Australia

Method 3 of 3: Treating a bite

  1. 1 The bite of ctenizides is not dangerous to humans. If you are bitten by a spider, you may experience slight pain and swelling. But since ctenisides are often confused with venomous funnel spiders, it is advisable to seek medical attention if symptoms worsen. Ideally, it is advisable to catch the spider so that its species can be identified.

Tips

  • Some species build their hatches in crevices in trees, but most ctenisides do burrow in the ground.
  • Females usually live up to 20 years, while males are only 5 years old. Ctenisides are the subject of hunting for road wasps.

Warnings

  • The door at the entrance to the burrow is very difficult to see, because the ctenisides mask the entrance with soil and plant material. Although these spiders are not aggressive, they can attack you if they sense danger, so it is advisable to wear gloves when removing leaves.
  • Funnel and mouse spiders are often confused with ctenisides.
