Myrmica lobulicornis - "Lobed-Antenna Myrmica"
Ready to delve into the fascinating world of Myrmica lobulicornis? These reddish-brown ants, often simply called Lobed-Antenna Myrmica by us ant enthusiasts, are a real gem for your formicarium. Workers are pretty robust, rocking shades from dark reddish-brown to almost black, with their head and gaster typically a bit darker than their thorax. What really sets them apart and gives them their name is that distinctive vertical flange, or 'lobe,' on the bend of their antennal scape – it's a super cool identifying feature for this Myrmica species! These ants are known for their somewhat leisurely, ground-based foraging style and are actually one of the chillest Myrmica species when it comes to aggression, making them a less 'spicy' option for your setup. Typically, adult workers measure in at a respectable 4 to 5 mm, making them a decent size for observation.
- Difficulty: Medium
- Origin & Habitat: Europe, Central Asia in Undisturbed natural and semi-natural habitats like upland moor, lowland heath, rough grassland, and open woodland, often found under stones in more open areas..
- Colony Type: More commonly monogyne, but polygyny can occur., semi-claustral (queen forages for food during founding) founding.
- Size & Growth:
- Queen: 5.5-6.5mm
- Worker: 4-5mm
- Colony: Small (hundreds) to Medium (thousands) (up to a few thousand workers).. Medium growth.
- Antkeeping:
- Temperature: Preferred temperature explanation: Room temperature (around 21-24°C) is generally suitable. Providing a slight heat gradient (e.g., heating one part of the nest) allows the ants to find their preferred temperature zone. Avoid overheating..
- Humidity: Preferred humidity explanation: Requires high humidity, typically between 50-70% in the nest. Consistent moisture is crucial to prevent dehydration, as Myrmica species are prone to drying out. A moist substrate or a water source in the nest is essential..
- Diapause: Required. 3-5 months at 5-10°C.
- Nesting: Preferred nest preference explanation: Thrives in naturalistic setups simulating their wild nests. Nests commonly found in the ground or under stones. Suitable artificial nests include plaster, Ytong, or natural setups with soil and sand elements. Ensure good moisture retention..
- Behavior: Low (towards handler, relatively low towards other ants compared to other Myrmica) aggressiveness.
- Common Issues: Mold in nest, Mites, Humidity fluctuations, Queen stress, Colony stalling (if diapause not properly provided).
When identifying your Myrmica lobulicornis, you'll notice some neat distinctions, especially if you're comparing them to their close cousin, Myrmica lobicornis. Keep an eye out for a slightly wider frons and generally smaller scape-lobes on their antennae. The most defining trait, however, is that prominent vertical flange-a little 'lobe'-right on the bend of their antennal scape. It’s what gives these ants their unique 'lobed horn' name! Their overall aesthetic is a lovely dark reddish-brown, often with their head and gaster taking on a deeper, darker hue compared to their midsection. This makes them a visually appealing ant species for any burgeoning ant colony.
Observing your Myrmica lobulicornis colony in their outworld, you'll likely notice their distinctive foraging behavior. Unlike some of their more frantic Myrmica relatives, these workers tend to be quite slow and a bit hesitant in their movements. They’re primarily ground foragers, preferring to explore the substrate rather than scaling up vegetation. While they might not be the most avid honeydew tenders, offering a diverse diet of small feeder insects and a good sugar water or honey-dew solution will keep your ant colony thriving and well-fed. Their natural diet leans heavily towards scavenged insect material, so replicating that is key to their health and growth.
Good news for antkeepers! While the Myrmica genus has a reputation for being a bit feisty, Myrmica lobulicornis is actually one of the more mellow ant species in the group, especially towards us humans. Yes, they do have a sting, but they're highly unlikely to use it unless they feel truly threatened. This low-aggression trait makes them a fantastic and less intimidating choice for your ant collection.
In the wild, Myrmica lobulicornis typically establishes their ant nests in more open areas, often directly within the soil or tucked away beneath stones. You won't usually spot elaborate above-ground structures, as they prefer a more discreet nesting approach. To truly make your colony feel at home and encourage optimal ant behavior, consider a formicarium setup that mimics these natural conditions. Providing ample substrate, whether it’s a soil-based nest or a Ytong setup with moist chambers, along with some strategically placed rocks or cork bark for hiding, will go a long way in ensuring your ants thrive.
