Fire ants, scientifically known as Myrmica rubra, aka Red Ant in the UK, are a captivating species that have piqued the interest of ant enthusiasts and researchers alike. These small but mighty creatures have garnered attention due to their intriguing behaviour, potent stings, and unique nesting habits.
This "boss" style walk sets them apart from other ant species and adds to their captivating allure.
While they are commonly referred to as fire ants, they do not possess the fiery red colouration often associated with other fire ant species. Instead, Myrmica rubra showcases a dark red or brownish-orange hue, making it easily distinguishable from other ant species. They are also known as European Fire Ant and Red ants in the UK.
You might not be familiar that this species has two types of queen ants, one is bigger than the workers, so around 7-8mm and the other, aka microqueen, is similar in size to the workers, 5-6mm. How can you identify a queen? The queen's thorax (middle part of the body) is way bigger and more muscular than the workers'.
Very easy to keep, so suitable for beginner ant keepers, they have a potent sting, and if you get stung, it's like a stinging nettle. Please keep this in mind and wear nitrile gloves while handling them.
Ant Farm requirements:
Air humidity: outworld: 30 - 50% and in the nest: 65 - 80%;
Temperature: outworld: overnight 18 and maximum daily temperature 28°C. In the nest area: 21 - 25°C.
Suitable ant farms are the A7 Ant Farm and the A6 Complete Ant Setup. If you'd like to monitor the temperature and humidity levels inside the ant farm, then we'll recommend the A7 Plus and A6 Ant Farm Kit with Meter.
Nesting Habits:
Myrmica rubra nests are typically found in areas with high humidity, such as meadows, grassy landscapes, rotten wood or mossy regions. They exhibit a preference for nesting in moss, as it provides an ideal habitat for their colonies.
Feeding Preferences:
Fire ants are voracious eaters, displaying a preference for both protein-rich foods and sugary substances like our Ant nectar. Boil insects before you give them to your colonies. Our protein jelly is a good, convenient way to feed your queens and workers all they need.
Frequently Asked Questions About Fire Ants (Myrmica rubra)
Does Myrmica rubra sting?
Yes, Myrmica rubra (European fire ants) can sting. Unlike many UK ant species that only bite, fire ants possess a stinger connected to venom glands. Their sting typically causes a sharp burning sensation (hence the name "fire" ants), localised swelling, and itchiness that may last several days. However, their stings are generally less severe than those of imported fire ant species like Solenopsis invicta.
Do we have red ants in the UK?
Yes, the UK is home to Myrmica rubra, commonly known as European fire ants or red ants. They are native to the UK and widespread throughout England, Wales, and parts of Scotland. Unlike the invasive Red Imported Fire Ant (Solenopsis invicta) found in the United States, Myrmica rubra is part of the natural UK ecosystem.
What happens if you get bitten by a fire ant?
If stung by a Myrmica rubra fire ant, you'll typically experience:
1. An immediate, sharp, burning pain
2. Redness and swelling around the sting site
3. Itchiness that may last 2–3 days
4. Small raised bumps or pustules in some cases
Are fire ants harmful?
Myrmica rubra fire ants are generally not seriously harmful to humans, though their sting can cause temporary discomfort. Unlike the more aggressive imported fire ants found elsewhere, European fire ants typically only sting when directly threatened or if their nest is disturbed. They pose no significant health risk to most people beyond mild pain and irritation. For ant keepers, they make fascinating subjects when proper precautions are taken.
How do you tell if it's a fire ant?
You can identify Myrmica rubra (European fire ants) by these distinctive features:
- Size: Workers measure 4-6mm in length
- Colour: Reddish-brown body with slightly darker abdomen
- Structure: Two-segmented waist (petiole and postpetiole)
- Antennae: Bent/elbowed with 12 segments ending in a 3-segmented club
- Spines: Two visible spines on the thorax
- Behaviour: Aggressive defence when the nest is disturbed
- Habitat: Often found in moist soil under rocks, logs, or in garden areas
