The Rusty Spider Wasp, also known by its scientific name Trypoxylon rubicum, is a species of wasp that belongs to the family Crabronidae. These wasps are commonly found in various parts of the world, including North America, and are known for their distinctive rusty or reddish-brown coloration. The Rusty Spider Wasp is a relatively small wasp, typically measuring between 1/2 to 1 inch in length, with a slender body and long, thin legs. One of the key identification features of this wasp is its rusty-colored body, which can range in shade from a light reddish-brown to a darker, more metallic brown. The wasp's body is also covered in fine hairs, giving it a slightly fuzzy appearance.
Physical Characteristics and Behavior
Rusty Spider Wasps are known for their solitary behavior, with individual wasps building their own nests and caring for their young. These wasps are also skilled hunters, feeding on spiders and other small insects to provide food for their larvae. The wasp’s stinger is used to immobilize its prey, and is also used for defense against potential threats. In terms of physical characteristics, the Rusty Spider Wasp has a number of distinctive features, including its rusty-colored body, long legs, and prominent mandibles. The wasp’s wings are also relatively long and narrow, allowing it to fly quickly and maneuver with ease.
Habitat and Nesting
Rusty Spider Wasps are typically found in areas with an abundance of spiders and other small insects, such as gardens, forests, and meadows. These wasps are also known to nest in a variety of locations, including hollow reeds, abandoned burrows, and even man-made structures like buildings and bridges. The wasp’s nest is typically constructed from a combination of mud and plant material, and is shaped like a long, narrow tube. The female wasp will lay her eggs inside the nest, and then provision the nest with food for the developing larvae. The nest is also protected by a hardened mud cap, which helps to prevent predators and other wasps from accessing the nest.

| Wing shape | Long and narrow |
| Mandibles | Prominent and strong |
Life Cycle and Development
The life cycle of the Rusty Spider Wasp typically begins in the spring, when the female wasp emerges from her winter hiding place. The female will then start building her nest, using a combination of mud and plant material to construct the nest’s walls and cap. Once the nest is complete, the female will lay her eggs inside the nest, and then provision the nest with food for the developing larvae. The larvae will feed on the food provided by the female, and will eventually spin a cocoon and pupate. The adult wasp will then emerge from the cocoon, and will start the cycle over again. The entire life cycle of the Rusty Spider Wasp can take several weeks to several months to complete, depending on factors such as food availability and climate.
Predators and Defense
Rusty Spider Wasps have a number of predators that feed on them, including birds, spiders, and other wasps. These wasps are also known to be aggressive when threatened, and will use their stinger to defend themselves against potential threats. The wasp’s stinger is capable of delivering a painful sting, and is also used to immobilize prey. In addition to their stinger, Rusty Spider Wasps also have a number of other defense mechanisms, including their ability to fly quickly and maneuver with ease. These wasps are also able to mimic the appearance of a spider, which can help to deter potential predators.
