Virginia's diverse ecosystem supports a wide variety of wasp species, ranging from the beneficial to the potentially problematic. Understanding the different types of wasps found in the Commonwealth is crucial for both safety and appreciating the vital role they play in the environment. This guide explores common wasp types in Virginia, their identifying characteristics, and how to interact with them safely.
What are the Most Common Wasps in Virginia?
Several wasp families are prevalent throughout Virginia. Some of the most common include:
-
Yellow Jackets (Vespula and Dolichovespula): These highly social wasps are easily recognized by their bright yellow and black stripes. They are known for their aggressive nature, especially when defending their nests. Yellow jackets are scavengers and feed on both insects and sugary substances, often attracted to picnics and outdoor gatherings. Several species exist within Virginia.
-
Paper Wasps (Polistes): These wasps build distinctive open-comb nests, usually under eaves, decks, or other sheltered locations. They are generally less aggressive than yellow jackets but will sting if provoked. Their bodies are typically longer and more slender than yellow jackets, with a variety of color patterns depending on the species.
-
Bald-faced Hornets (Dolichovespula maculata): While their name suggests otherwise, these are actually a type of yellow jacket. They are easily identified by their mostly black bodies with white markings on their face and thorax. They build large, football-shaped nests high in trees or shrubs. Like yellow jackets, they are capable of stinging multiple times and can be aggressive when defending their nests.
-
Cicada Killers (Sphecius speciosus): These large, solitary wasps are impressive in size but are generally not aggressive unless directly threatened. They are named for their habit of paralyzing cicadas to feed to their larvae. Males are often seen patrolling territory, but only the females sting.
-
Mud Daubers (Sceliphron): These solitary wasps are known for their distinctive nests made of mud, often found in sheltered areas such as sheds, garages, and under eaves. They are not aggressive and rarely sting unless handled roughly. Different species create different nest structures.
What is the Difference Between a Wasp and a Hornet?
The terms "wasp" and "hornet" are often used interchangeably, causing confusion. Technically, hornets are a type of wasp belonging to the genus Vespa. In Virginia, the most commonly encountered "hornet" is actually the bald-faced hornet, which, as mentioned above, is a species of yellow jacket. The key difference is taxonomic: hornets belong to the genus Vespa, while many other stinging insects with similar appearances are simply categorized under the broader term "wasp."
How Can I Identify Different Wasp Species in My Yard?
Accurate identification requires careful observation of physical characteristics, including size, color patterns, nest structure, and behavior. High-quality photographs can be helpful for consulting online resources or entomologists for accurate identification. Field guides specific to Virginia insects can also be invaluable. Remember that attempting close-up observation without proper safety precautions is risky.
Are Wasps Dangerous?
The danger posed by wasps varies greatly depending on the species and individual circumstances. Yellow jackets and bald-faced hornets are the most aggressive and pose the greatest risk due to their propensity to sting repeatedly. Allergic reactions to wasp stings are a serious concern, and individuals with known allergies should take appropriate precautions. Most other wasp species are relatively docile and unlikely to sting unless threatened.
How Can I Get Rid of Wasps?
If you have a wasp nest near your home or property, it’s advisable to consult with a pest control professional. Attempting to remove a nest yourself can be dangerous and may lead to multiple stings. Professional exterminators have the experience and equipment to handle wasp removal safely and effectively.
What Do Wasps Eat?
Wasp diets vary widely depending on the species. Some, like yellow jackets, are omnivorous, feeding on both insects and sugary substances. Others, such as cicada killers, specialize in paralyzing and feeding their larvae specific prey. Many wasps play a crucial role in pest control by preying on other insects.
This guide provides a broad overview of common wasps found in Virginia. Remember that safe observation and responsible interaction are key to coexisting peacefully with these fascinating insects. For specific identification or concerns about wasp nests, always consult with a qualified professional.
