Trapdoor theraphosids

Written by Zoltán Mihály Lestyán

The phenomenon when a spider covers its burrow with a so-called "trapdoor" is well known and characteristic in some mygalomorph families (e.g., Antrodiaetidae, Ctenizidae) and in the family Liphistiidae, but we can also find a few examples of this behaviour in the tarantula family: Theraphosidae.
