Round 2: Tossup 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 quipped that God must have had an “inordinate fondness” for these animals due to their abundance. 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■
ANSWER: beetles [accept Coleoptera before mentioned; accept bombardier beetles or rhinoceros beetles or Hercules beetles or stag beetles or diver beetles]
