The Stinky World of Pinacate Beetles:
Nature's Little Stink Bombs

Stinkbugs

Ever stumbled upon a jet-black beetle doing a headstand in your backyard? Chances are, you've just met a Pinacate Beetle, also known as a stink bug or clown beetle. Don't let their circus-like antics fool you – these little guys pack a punch (or rather, a stench) that'll make you think twice about messing with them!

Description

The name "pinacate" comes from the Aztec word "pinacatl," meaning "black beetle." But that's not their only moniker. They're also called darkling beetles (sounds like something out of a fantasy novel, right?) and stink bugs – for reasons you'll soon discover. And let's not forget "clown beetles," a nod to their hilarious defensive pose.

Picture a tiny, shiny black low-rider cruising through your garden – that's a Pinacate Beetle for you! These tough little cookies range from 0.4 to 1.4 inches long and rock a sleek, oval shape. Some are smooth as polished onyx, while others are as rough as sandpaper. A few fancy varieties even sport hair-like structures and what looks like a tail (spoiler alert: it's a pair of unused wings).

Range

If you live west of the Mississippi, congratulations! You're in Pinacate Beetle territory. These resilient bugs have conquered diverse landscapes, from sandy dunes to rocky mountains, and even made it to the islands off California's coast. But if you want to see the biggest, worst (and smelliest) of the bunch, head to the desert – it's their favorite hangout spot.

The Stink Bug's Secret Weapon

Now, here's where things get interesting. When threatened, pinacate beetles pull off a move that would make any yoga instructor proud – they do a headstand! But that's not all. As they strike this comical pose, they unleash their secret weapon: a foul-smelling spray that can reach up to 20 inches away.

This stinky secretion is their way of saying, "Back off, buddy!" And trust me, most predators get the message loud and clear. The spray isn't harmful to humans, but it's not something you want in your eyes or mouth. Good luck washing it off – this stuff clings like nobody's business.

Habits and Habitat

These little guys aren't picky eaters. They munch on dead plant matter in the wild, acting like nature's tiny recyclers. But in captivity, they've been known to chow down on apples, lettuce, and dog food. Talk about adapting to the suburban lifestyle!

Getting Rid of Stink Bugs

You might wonder, "What if these stinky visitors decide to crash at my place?" Don't worry; we've got you covered. Here are some tips to keep your home stink-bug-free:
1 Seal the deal: Check for cracks around windows, doors, and the foundation. Seal them up to prevent these sneaky bugs from entering.
2 Light's out: Stink bugs are attracted to bright lights. Use yellow or sodium vapor lights outside, or keep outdoor lighting to a minimum.
3 Vacuum power: If you spot stink bugs inside, vacuum them up. Remember to dispose of the vacuum bag immediately to avoid a lingering smell.
4 Natural repellents: Try planting mint or lavender around your home – stink bugs hate these scents.
5 The soapy solution: Mix water and dish soap in a spray bottle. This concoction can kill stink bugs on contact without releasing their odor.

Remember, while Pinacate Beetles might be a nuisance, they play a vital role in our ecosystem. So, try to relocate them outdoors whenever possible rather than resorting to harmful pesticides.

Notes

The larvae of certain Eleodes species are also known as false wireworms, and they are a pest of some commercial crops in the Midwest. Larvae are slender, shiny, darkish green to brown, and hard bodied. They feed on the seeds and seedlings of wheat, sorghum, all oilseeds, grain legumes and cereals, particularly in light, draining soils with a high organic content. Fine seedling crops like canola and linola are particularly susceptible.
