Micro Monsters with David Attenborough

David Attenborough continues his bug-eyed view of the world of creepy-crawlies, revealing how predators defuse the defences of their prey. Highlights include the cockroach wasp, busy preparing a tasty - and very live - treat for its young, the whirligig beetle, which employs a water-based radar system, and the jumping Portia spider, which feeds on other arachnids.

A close-up view of sex, bug-style, as David Attenborough talks viewers through the different ways in which creepy-crawlies reproduce. Size matters for the minuscule male orb spider, creepily sneaking up on its intended and trying to mate without her noticing, while theres no rest for the lothario-like butterfly, which has plenty of notches on its proverbial bedpost. However, the harvestman spider has no use for sex at all, and reproduces by cloning itself.

Watching the fascinating display of leafcutter ants at the Natural History Museum in London is one of my favourite ways to while away a few hours, but David Attenborough is operating on a much grander scale here in the last in the series. In Argentina he observes some cousins of the leafcutters who are part of a community so vast it spans an entire continent. It’s one of the mandible-dropping facts in a look at one of the key inventions of arthropods: colonies. From termites and honey bees to the leafcutters, it seems that if you want to get ahead, you move to the big city.
