Q & A
  • What is the unique adaptation of the Touch Me Not Balsam in the Lake District?

    -The Touch Me Not Balsam has the ability to exude excess moisture from its leaves at night, which is particularly handy given the waterlogged soils of the Lake District.

  • How do the seed heads of Touch Me Not Balsam affect the netted carpet moth caterpillar?

    -The seed heads of Touch Me Not Balsam explode, which can hurt the netted carpet moth caterpillars that feed on them. The caterpillars have no warning when these explosions occur.

  • What is the significance of the hot rod ant in the Namib Desert?

    -The hot rod ant is able to survive in the extreme heat of the Namib Desert by keeping its body elevated above the scorching surface using its long legs, thus avoiding heatstroke.

  • How do ant lions ambush their prey in the desert?

    -Ant lions create cone-shaped traps in the sand. When an ant walks into the trap, the walls are angled in such a way that the sand slips beneath the ant's feet, causing it to fall into the center where the ant lion waits to attack.

  • What defense mechanism does the bombardier beetle use against predators?

    -The bombardier beetle can create a chemical reaction within its body that results in boiling caustic liquid exploding out of its abdomen. It can pulse this jet up to 500 times a second to keep its rear end cool enough to prevent being cooked.

  • What is the extraordinary survival skill of New Zealand's wΔ“tā, or giant water beetle?

    -The wΔ“tā can tolerate over 80 percent of its body freezing solid and can do so for weeks at a time. It has developed special proteins that prevent ice crystals from forming inside its cells, allowing it to survive near-lethal temperatures.

  • How do Japanese bees defend themselves against a hornet scout?

    -Japanese bees lure the hornet scout inside the hive, then surround it with vibrating bodies, causing the hornet to overheat. The bees have a heat tolerance two degrees above that of their enemy, which allows them to survive the heat generated.

  • What is the unique collective behavior of driver ants during the rainy season?

    -During the rainy season, driver ants form extraordinary hunting trails. Large soldier ants line the trail, protecting the smaller workers inside, creating an impregnable barricade against predators and other threats.

  • How do driver ants deal with dangerous pests like scorpions?

    -Driver ants are not deterred by the scorpion's deadly sting. They attack byεˆ†ε·₯合作, with some ants prying open the scorpion's body plates and others immobilizing its sting, eventually dismembering and carrying the body back to feed the nest.

  • What is the role of the driver ant super brain in the colony?

    -The driver ant super brain is formed by millions of interlocking ants that communicate using pheromones. Individual ants are not intelligent, but the collective network they form allows the colony to make decisions for the benefit of the entire hive.

  • How do locusts change their behavior when food becomes scarce?

    -When food begins to run out, winged adult locusts release pheromones signaling the group to move on. As groups merge, they form swarms that travel with the wind, seeking out new areas with more vegetation.
