Wales Volunteers Find Beetle with Poo Umbrella Defense

A beetle larva with a prehensile anus might sound like science fiction, but thanks to volunteer wildlife recorders in Wales, we now know this extraordinary creature lives among us.

In Ceredigion, Wales, a network of passionate volunteers spends their time moving slowly through fields and forests, looking hard at the small things most people miss. Their work recently revealed a tortoise beetle larva on knapweed, a tiny emerald green spiked creature with one of nature's most creative defense mechanisms.

The larva collects its own waste to form a protective shield, essentially creating a poo parasol that it waves at predators. This outrageously inventive survival strategy works so well that the species has thrived for millions of years.

But this bizarre beetle is just one discovery among thousands. Carys May from the West Wales Biodiversity Information Centre regularly identifies species during Wildwatch recording mornings, from mining bees that exit flowers covered in pollen powder to marmalade hoverflies that migrate from the continent at great heights.

These recorders are the unsung heroes of conservation. Every county has experts on everything from moths to dragonflies who identify species, coordinate sightings, and keep meticulous records, all done voluntarily.

Steve Chambers, Ceredigion's botanical recorder, explains that even landscapes that seem ordinary often hide rare treasures. Walking through 19 acres of rough grassland near Cwm Tydu, he identified a small-flowered sweet briar rose whose crushed leaves smell like apples, a species rare enough that he might consult the rose referee, another level of specialist volunteer.

Why This Inspires

These volunteers work down on hands and knees, gathering vital data that tracks wildlife trends and informs conservation efforts. Their dedication means that crucial scientific information gets collected even in areas without formal research funding.

More importantly, they share their discoveries with the public, transforming how we see the world around us. Without their expertise, most of us would walk past fields thinking they were empty of interest.

Instead, these recorders reveal that there's no such thing as an ordinary field. Every patch of land contains microscopic dramas, evolutionary marvels, and survival strategies that put human ingenuity to shame.

Their slow, careful observation proves that the most amazing discoveries don't require expensive expeditions to remote jungles. Sometimes you just need to look harder at what's already here, preferably with someone who knows where to look and what to look for.

Thanks to these volunteers, we get to learn about beetles with poo umbrellas, and that makes the world a much more wonderful place.
