        "content": "In West Virginia, yellowjackets\u2014social wasps in the genera *Vespula* and *Dolichovespula*\u2014are fairly common. The size of a yellowjacket depends on whether it\u2019s a worker, male, or queen, and which species it is. Here\u2019s a breakdown of what to expect:\n\n---\n\n## \ud83d\udccf Typical Sizes\n\n- **Workers**: ~3/8 to 5/8 of an inch long (approximately 9-16 mm). ([pestworld.org](https://www.pestworld.org/pest-guide/stinging-insects/yellowjackets/?utm_source=openai))  \n- **Queens**: Larger than workers, often up to ~3/4 of an inch (\u2248 18-20 mm), depending on the species. ([extension.msstate.edu](https://extension.msstate.edu/sites/default/files/publications/publications/P3950_POD_Hornets_webREV.pdf?utm_source=openai))  \n\n---\n\n## \ud83d\udc1d Examples of Common Species & Their Sizes\n\n- **Eastern yellowjacket (*Vespula maculifrons*)**  \n  Workers are about **1.25 cm** (\u2248 0.49 in), while queens reach around **1.8 cm** (\u2248 0.71 in). ([animaldiversity.org](https://animaldiversity.org/accounts/Vespula_maculifrons/?utm_source=openai))  \n\n- **Common/Aerial yellowjacket (*Dolichovespula arenaria*)**  \n  Workers are medium size, roughly **14-17 mm** (\u2248 0.55-0.67 in). ([inaturalist.org](https://www.inaturalist.org/posts/114985-table-comparing-common-aerial-yellowjacket-dolichovespula-arenaria-western-yellowjacket-vespula-pensylvanica-and-european-paper-wasp-polistes-dominula?utm_source=openai))  \n\n- **Bald-faced hornet (*Dolichovespula maculata*)**, which is actually an aerial yellowjacket  \n  These are one of the larger yellowjackets: about **5/8 to 7/8 in** long (\u2248 16-22 mm). ([cals.cornell.edu](https://cals.cornell.edu/integrated-pest-management/outreach-education/whats-bugging-you/bees-and-wasps/identifying-bees-and-wasps/yellowjackets-and-baldfaced-hornets?utm_source=openai))  \n\n---\n\nIf you tell me which species you saw (color pattern, where it was nesting\u2014ground or aerial), I can help narrow it down further so you can get an accurate estimate."
