Round 2: Tossup 1

Questions 1. The larval form of an aquatic species of these animals is known as the “water tiger” due to its appetite. A type of these animals uses its pygidial glands to mix hydroquinone and hydrogen peroxide in an explosive spray. J. B. S. Haldane (15[1])quipped that God must have had an “inordinate (-5[1])fondness” for these (15[1])animals due to their abundance. (15[1])These animals fly using wings encased in hardened (*) elytra. Some of these non-ant insects in the “rhinoceros” subfamily can lift more than 100 times their body weight. For 10 points, name these insects in the order Coleoptera which make up 25% of all animal species and include fireflies, ladybugs, and scarabs. ■END■ (10[1])

ANSWER: beetles [accept Coleoptera before mentioned; accept bombardier beetles or rhinoceros beetles or Hercules beetles or stag beetles or diver beetles]
