German yellowjacket vs Southern yellowjacket
These two are easy to mix up. Here's how to tell a German yellowjacket from a southern yellowjacket, and whether either one bites or stings.
German yellowjacket
Vespula germanica
Southern yellowjacket
Vespula squamosa
≠The key differences
V. germanica has different abdominal stripe shapes and a more widespread global distribution; behavior and nesting are similar but pattern details differ.
⚖︎Side by side

|---|---|---|
| To humans | Painful sting | Painful sting |
| Size | Workers 10-16 mm; queens 18-22 mm | Workers 10-16 mm; queens up to 18-20 mm |
| Colours | Yellow, Black, Brown (abdomen/shaded areas) | Yellow, Black, Pale brown (nest paper) |
| Family | Vespidae | Vespidae |
| Habitat | Nests in cavities (wall voids, roof spaces, rodent burrows, hollow trees) and sometimes underground; forages in gardens, parks, farms, and around human food sources. | Woodland edges, fields, urban and suburban areas; nests in soil cavities, under logs, inside wall voids and other protected cavities |
| Range | Native to Europe, northern Africa and temperate Asia; introduced and established in North and South America, southern Africa, Australia, New Zealand and several islands. | Eastern and southeastern United States, west into the southern central US, and south through Mexico into Central America |
| Active | Active spring to autumn in temperate regions; most visible and abundant in late summer and early autumn, daytime foragers. | Spring to late fall; most abundant and aggressive in late summer and early fall during colony maturity |
| Pest? | Yes | Yes |
🔍How to spot a German yellowjacket
- Bold alternating yellow and black bands on the abdomen with characteristic black triangular markings on the second abdominal segment.
- Compact, stocky body shape typical of yellowjackets; workers 10-16 mm, queens larger.
- Face often shows a darker 'mask' of black with yellow highlights; compare banding pattern to other local Vespula species for reliable ID.
- Nests commonly found in cavities (walls, attics, rodent burrows) and sometimes shallow underground.
🔍How to spot a southern yellowjacket
- Yellow-and-black banded abdomen and two lengthwise yellow stripes on top of the thorax; queens have a mostly orange-brown abdomen.
- Size: workers about 10-16 mm, queens larger and bulkier.
- Nesting site: often subterranean or in cavities; unusually large colonies or aggregations of combs may indicate V. squamosa involvement.
- Behavior: many workers foraging together on fruit or at human food sources, aggressive when nest disturbed.
?Frequently asked questions
What is the difference between a German yellowjacket and a southern yellowjacket?
V. germanica has different abdominal stripe shapes and a more widespread global distribution; behavior and nesting are similar but pattern details differ.
Is a German yellowjacket or a southern yellowjacket more dangerous?
German yellowjacket: Painful sting. Southern yellowjacket: Painful sting. Workers can sting repeatedly and deliver painful stings; reactions range from local pain, swelling and redness to severe allergic anaphylaxis in sensitized people. Southern yellowjackets can sting repeatedly; stings are painful and can cause severe allergic reactions in susceptible people (anaphylaxis).
Identification from photos is never certain: don't handle insects you can't identify, and get medical advice for bites, stings or allergic reactions.
