Cataglyphis douwesi

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to southern Spain, specifically the Cádiz region on the south-Atlantic coast of the Iberian Peninsula. This species inhabits arid to semi-arid Mediterranean habitats, typically nesting in open ground with sparse vegetation ^[1][2].
• Colony Type: Colony structure is unconfirmed for this specific species. Based on typical Cataglyphis patterns, likely single-queen colonies.
• Size & Growth:
  • Queen: Size data unavailable for this species, inferred from Cataglyphis genus (~9-12mm)
  • Worker: Size data unavailable for this species, inferred from Cataglyphis genus (~4-7mm)
  • Colony: Estimated up to several hundred workers based on related species
  • Growth: Moderate, estimated based on genus patterns
  • Development: Development time is unconfirmed for this species. Based on related Cataglyphis species, expect 8-12 weeks at optimal temperature. (Development time is inferred from related species, specific data for C. douwesi is not available.)
• Antkeeping:
  • Temperature: Keep at 24-28°C with a warm gradient. Cataglyphis are heat-tolerant and benefit from temperatures on the warmer end of what most ant species prefer. A heating cable on one side of the nest creates the ideal gradient ^[3].
  • Humidity: Low to moderate, aim for 40-60% relative humidity. These are desert/arid-adapted ants that prefer drier conditions. Allow the nest to dry out between waterings rather than keeping it constantly moist ^[3].
  • Diapause: Yes, provide a winter rest period of 8-12 weeks at 10-15°C. This species originates from temperate Spain and will benefit from a hibernation period during winter months ^[3].
  • Nesting: Y-tong (AAC) nests work well for this species. The narrow chambers and passages suit their body size. Naturalistic setups with sand or soil substrates also work. Ensure the nest has some dry areas since they prefer arid conditions ^[3].
• Behavior: Active and fast-moving foragers. They are diurnal, typically foraging during the warmer parts of the day, this is characteristic of the genus as they are adapted to tolerate high temperatures. Workers are not particularly aggressive but will defend the nest if threatened. As Formicinae ants, they lack a functional sting and instead spray formic acid as their primary defense. Escape risk is moderate, use standard formicarium barriers but they are not known for being particularly good escapers compared to some other genera.
• Common Issues: limited distribution data means exact habitat requirements are uncertain, slow colony growth compared to tropical species may frustrate beginners, hibernation requirements are often underestimated by new keepers, wild-caught colonies may be difficult to find due to limited range, dry nesting conditions must be balanced with providing drinking water

Nest Preferences

Cataglyphis douwesi nests in open ground in arid to semi-arid habitats. In captivity, Y-tong (AAC) nests work well because they provide the narrow chambers and passages that suit this species body size. You can also use naturalistic setups with a sand or soil mixture. The key is providing a gradient, some areas should be warmer and drier while cooler areas allow the ants to regulate their temperature. Avoid overly humid conditions as this species is adapted to drier Mediterranean climates. A test tube setup can work for founding colonies, but be prepared to move them to a larger formicarium once the colony reaches 30-50 workers. ^[1][2][3]

Feeding and Diet

Cataglyphis ants are primarily predatory and scavengers. In captivity, offer a varied diet including small insects like fruit flies, pinhead crickets, and mealworms. They also readily accept sugar sources such as honey water or sugar water. Feed protein prey 2-3 times per week and keep a constant sugar water supply. Unlike some ants, they are not known for tending aphids or collecting honeydew extensively. Fresh water should always be available. Remove uneaten prey after 24-48 hours to prevent mold issues. ^[3]

Temperature and Seasonal Care

These ants are heat-tolerant and prefer warmer conditions than many European ant species. Keep the nest at 24-28°C during the active season, with a slight gradient allowing workers to choose their preferred temperature. A heating cable placed on one side of the nest works well to create this gradient. During winter, provide a hibernation period of 8-12 weeks at 10-15°C. This simulates the natural seasonal cycle they would experience in their native Spain. Reduce feeding during hibernation and avoid disturbing the colony. Gradual cooling in autumn helps prepare them for winter rest. ^[3]

Behavior and Foraging

Cataglyphis douwesi workers are fast-moving and diurnal, characteristic of the genus. They are adapted to forage in warm conditions and will be most active when the nest is heated. Workers search for food individually rather than using chemical trails to recruit nestmates. They are not particularly aggressive but will defend the colony if threatened. Their black coloration helps absorb heat while foraging in sunny conditions. The workers are slender and built for speed, so they can cover considerable distances while foraging. Provide a foraging area that allows them to explore and find food. ^[1][2]
