Preferred Nesting Locations

Great Black Wasps, also known as Sphex pensylvanicus, are fascinating creatures that can be found in a variety of nesting locations. These wasps are solitary insects, meaning they do not live in colonies like other wasp species. Instead, each female wasp builds her own nest and tends to her own offspring. Let’s explore some of the preferred nesting locations of these remarkable insects.

Underground Burrows

One of the most common nesting locations for Great Black Wasps is underground burrows. These wasps are excellent diggers and have the ability to excavate tunnels in loose soil or sandy areas. They create burrows that can extend several inches or even feet below the ground surface. These underground chambers serve as a safe haven for their developing offspring.

The female wasp carefully selects a suitable nesting site and starts digging her burrow. She uses her powerful mandibles to move the soil and create a tunnel. Once the burrow is deep enough, she constructs individual chambers within it. Each chamber serves as a brood cell, where she will lay a single egg and provide provisions for the developing larva. The female then seals the chamber with soil, effectively protecting her offspring from predators and harsh environmental conditions.

Hollow Stems and Cavities

In addition to underground burrows, Great Black Wasps also take advantage of hollow stems and cavities for their nesting needs. These resourceful insects locate stems of plants or tree branches that have natural hollows or openings. They may also utilize existing empty cavities, such as those left behind by wood-boring beetles or other insects.

Once a suitable hollow stem or cavity is found, the female wasp meticulously inspects and prepares it for nesting. She clears out any debris or potential obstacles, ensuring a safe and clean environment for her offspring. She then constructs individual brood cells within the stem or cavity, similar to the underground burrows. Each cell contains an egg and provisions for the developing larva. The female carefully seals each cell, providing protection and security for her young.

Abandoned Rodent Nests

Great Black Wasps are opportunistic nesters and are known to make use of abandoned rodent nests. These nests, typically constructed by small mammals like mice or voles, provide a ready-made shelter for the wasps. The female wasp locates an abandoned nest, often hidden among tall grasses or nestled in the crevices of rocks or trees.

Once inside the abandoned nest, the female wasp inspects and modifies it to suit her needs. She may reinforce the structure with additional materials or make adjustments to create separate brood cells. These nests offer the advantage of insulation and protection, as they are already well-hidden and camouflaged. The female wasp takes advantage of this existing structure to lay her eggs and provide provisions for her offspring.
