Explaining Nature on Instagram: "Trapdoor spiders construct burrows with actual “hinged” doors, cleverly camouflaged to blend in with their surroundings. These doors are typically made from a combination of soil, silk, and plant material, allowing the spider to remain hidden while still being able to quickly open and close the entrance to their burrow for hunting or escaping predators.
