Tree Crickets: Smooth Talker
Male crickets bite holes in leafs to amplify their love songs and attract females. Once they mate, however, male sperm packets don’t fit inside the females’ bodies so a portion hangs out. The ever-ravenous females try to eat the packet before fertilization can occur. To distract her, the male sings and secretes a tasty goo from his back, feeding her until the eggs are fertilized.
