Arthro-Pod

Hello lovers of bugs, as well as bugs who are in love! In today's episode, we take a journey through the world of nuptial gifts within the arthropods and find out why sometimes it is best to wrap a gift before trying to go on a date. Tune in to learn the basics of why nuptial gifts exist and how they can help facilitate the mating process and generation of the next generation. This one is a bit "spicy" so if you listen with kids, prepare for some biological talk!
