Cataglyphis rosenhaueri (Iberian Desert Ant)
Cataglyphis rosenhaueri is a fascinating species of desert ant originating from the Iberian Peninsula, particularly the hot, dry regions of Spain. Like many members of the Cataglyphis genus, they are renowned for their incredible speed, long legs and ability to remain active in temperatures that would drive many other ant species into hiding.
These striking ants have a distinctive appearance, with a reddish-brown head and thorax contrasting beautifully against their glossy black gaster. Their long legs and excellent eyesight give them an almost spider-like appearance as they rapidly navigate their surroundings.
Queens typically measure around 12mm, with workers generally reaching approximately 5-9mm.
In the wild, colonies inhabit hot, dry and sparsely vegetated Mediterranean environments, often nesting within sandy or sandy-loam soils. They are particularly well adapted to exposed habitats and are most active during the warmer parts of the day, when they leave the nest to search for food.
Their speed is one of the most entertaining aspects of keeping this species. Workers can move incredibly quickly across the outworld and tend to be highly alert, making them an excellent species for keepers who enjoy watching active and constantly moving colonies.
Cataglyphis rosenhaueri are generally monogynous, meaning colonies typically contain a single queen, and mature colonies can reach several hundred workers. They can develop relatively quickly under suitable conditions, so providing additional space as the colony grows is an important consideration.
When it comes to feeding, these ants are straightforward and opportunistic. They readily accept a variety of small insects such as fruit flies, flies, mealworms and appropriately sized roaches, alongside a regular source of carbohydrates such as sugar water or honey water. Providing both protein (red runners are a favourite) and sugars (flavus nectar) will help support brood production and colony growth.
As a heat-loving species, C. rosenhaueri should be provided with a warm setup and, ideally, a temperature gradient. A warm nest area around 24-27°C with a warmer foraging zone between 27-32C can work well, while the outworld should remain comparatively dry.
Good ventilation is particularly important, as these ants are adapted to hot, xeric environments and do not appreciate persistently damp conditions.
A short period of cooler winter rest is commonly provided by keepers, with temperatures reduced to approximately 15-18°C for several weeks. This should be introduced gradually and adjusted according to the condition and seasonal cycle of the colony.
Overall, Cataglyphis rosenhaueri is a fantastic choice for keepers looking for a distinctive Mediterranean species with plenty of activity, impressive speed and a beautiful colour contrast. Their heat-loving nature and relatively rapid development make them a particularly rewarding species for intermediate and experienced ant keepers.
Important: It is illegal and strictly frowned upon to release any non-native ants into the wild.
