Episode 20: Thigmonasty in Prickly Pears and a Loveliness of Ladybugs

Plant movement in response to touch is called thigmonasty. The flowers of prickly pear cactus have stamens – the part of the flower topped with pollen – that move inward when touched. Daniel discusses a few reasons why this might be.

Then Casey regales us with a few fun facts about ladybugs. For example, they are voracious aphid eaters (even during copulation), and a group of them is called a Loveliness. Say what? I think I need to lie down for a minute.
