“We may think that gift giving is a purely human trait, but it turns out many other animals also treat their mates and companions.
If on Christmas morning, upon opening your annual gift of novelty socks, your feeling is that of crushing disappointment, you can at least be thankful that you’re not a female scorpionfly.
If you were, then the best you could look forward to at yuletide would be a ball of spit from the love of your life. Far from being disappointed though, female scorpionflies relish the tasty treat, rewarding their suitors with the opportunity to mate with them.”
