Behavior

The Lesser Vespillo Burying Beetle is one of nature's most dedicated and complex parents. Often referred to as a 'Sexton Beetle,' this species is famous for its ability to locate the carcasses of small vertebrates, such as mice or songbirds, from great distances using highly sensitive chemoreceptors on its antennae. Once a suitable carcass is found, a male and female pair will work together to excavate the earth beneath it, slowly sinking the body into the ground to protect it from larger scavengers and competing flies.

Unlike the vast majority of insects, these beetles exhibit biparental care. They strip the carcass of fur or feathers, roll it into a ball, and treat it with antimicrobial secretions to slow decay. After the eggs hatch in the nearby soil, the parents actively feed the larvae by regurgitating liquefied food. They are also frequently seen carrying 'hitchhiking' mites (Poecilochirus); these mites are not parasites, but partners that eat fly eggs on the carcass, helping the beetle's own offspring survive by reducing competition.

Camera Tips

Capturing high-quality footage of the Lesser Vespillo Burying Beetle requires getting your camera down to ground level. Since these beetles spend their lives navigating the leaf litter, place your AI camera on a tripod mount or a flat stone just 2–5 inches above the forest floor. Ensure the lens is angled slightly downward to capture the beetle's distinctive orange markings and black antennae. Because they are relatively small, a camera with macro capabilities or a close-focusing range is ideal for identifying the species accurately.

To guarantee a sighting, you can create a 'scent station.' Place a small piece of raw meat or a fresh, unseasoned chicken wing inside a small, sturdy mesh cage or a perforated container. This prevents local cats, foxes, or raccoons from carrying the bait away while allowing the beetle's keen sense of smell to lead it directly into your camera's field of view. Secure the container to the ground with a tent stake so the beetles can crawl around it without the 'bait' shifting out of frame.

Pay close attention to your camera's sensitivity settings. Beetles move with a jerky, rapid gait that can sometimes be missed by standard motion sensors designed for large mammals. Set your trigger speed to its highest setting and choose a multi-shot burst mode. If you are using an AI-powered camera, ensure the software is updated to recognize insects. While they are active both day and night, you will get the best color definition during the warm afternoon hours when their orange bands appear most vibrant against the dark soil.

Frequently Asked Questions

Unlike many other sexton beetles that are strictly nocturnal, the Lesser Vespillo is frequently active during the day (diurnal) and at twilight, though they can also be found moving at night during peak summer.

You can attract them by leaving a small amount of raw meat in a protected mesh box on the ground near a shady, wooded corner of your garden. Avoid using pesticides, as they are very sensitive to soil chemicals.

They primarily feed on small animal carcasses like mice or small birds. They also eat fly larvae (maggots) that they find on the carrion, which helps protect their own food source.

Yes, they are quite common in suburban gardens, especially those with plenty of mulch, leaf litter, and nearby shrubs or trees that provide a forest-like microclimate.

The easiest way is to look at the antennae. The Lesser Vespillo (Nicrophorus vespilloides) has entirely black antennae, while the very similar Common Burying Beetle (N. vespillo) has bright orange tips on its antennae.
