Cataglyphis sabulosa

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Desert regions of the Middle East and North Africa, specifically found in sand dunes in the southern Coastal Plain of Israel, Northern Sinai, Arava Valley, and across Egypt, Oman, Saudi Arabia, and UAE ^[2][3]. Nests are built in sand, typically close to vegetation spots, extending up to 1.5 meters deep ^[3].
• Colony Type: Strictly monogyne, colonies have a single queen. Queens are polyandrous, mating with 1-5 males. Workers can reproduce via thelytokous parthenogenesis if the queen dies, but only in queenless colonies ^[3][4].
• Size & Growth:
  • Queen: size data unavailable, no total length measurements found in research
  • Worker: size data unavailable, no total length measurements found in research
  • Colony: Small colonies, typically up to 300 workers, average around 186 workers ^[5][3]
  • Growth: Moderate, development takes 5-8 weeks from egg to adult at optimal temperature ^[3]
  • Development: 5-8 weeks (eggs reach adult stage within 5 weeks at 31°C, full development up to 2 months) ^[3] (Development was studied at 31±2°C in laboratory conditions. Under warmer captive conditions, development may be faster, under cooler conditions, slower.)
• Antkeeping:
  • Temperature: Keep at 28-32°C. This is a desert species that thrives in warm conditions. Laboratory colonies were successfully maintained at 31±2°C with natural 12:12 photoperiod ^[3]. A heating cable on one side of the nest creates a gradient allowing workers to regulate their temperature.
  • Humidity: Low to moderate. As a desert species, they prefer dry conditions. Keep the nest substrate moderately moist but allow portions to dry out. Avoid excessive moisture which can cause mold in desert species setups.
  • Diapause: Unknown for this species. Given its Middle Eastern distribution, it may have reduced activity in winter months but diapause requirements are not well-documented. Consider providing a cool period (15-18°C) for 2-3 months during winter if the colony shows reduced activity.
  • Nesting: Natural nesting is in sand dunes, with nests extending up to 1.5 meters deep ^[3]. In captivity, they do well in sandy substrates in naturalistic setups or Y-tong nests with sand-filled chambers. They prefer nesting in areas with some moisture at depth but access to drier areas as well.
• Behavior: These ants are active foragers, typical of the Cataglyphis genus. Workers search for food individually and are not particularly aggressive. They are not escape artists like some tiny ants, but standard escape prevention (Fluon barrier) is still recommended. Males participate in nuptial flights and will land at foreign colony entrances to mate ^[3]. Workers in queenright colonies do not reproduce, worker reproduction only occurs in queenless situations as an emergency measure ^[3]. As Formicinae ants, they spray formic acid as defense rather than using a sting.
• Common Issues: colonies are small and grow slowly, beginners may lose patience and overfeed, causing mold issues, desert species prone to mold if kept too humid, balance moisture carefully, queen death can trigger worker reproduction but colony may still fail without proper conditions, nuptial flights occur in early May, timing is specific and may be hard to replicate in captivity, small colony size means less buffer against mistakes, losses impact the colony more

Nest Preferences and Housing

In the wild, C. sabulosa builds nests in sand dunes, typically close to vegetation spots where the soil is more stable. Nests can extend up to 1.5 meters deep into the sand ^[3]. This deep nesting behavior helps them escape the extreme heat at the surface and maintain stable humidity levels.

For captive care, a naturalistic setup with a sandy substrate works best. You can use a mix of sand and soil (about 70:30 sand to soil) to give the colony digging opportunity while maintaining structure. A Y-tong nest with sand-filled chambers is also suitable. The key is providing depth, at least 10-15cm of substrate so they can create proper chambers.

Because they are a desert species, ventilation is important to prevent mold. However, they still need some humidity at the deeper levels where the brood is kept. A common approach is to keep one side of the nest slightly moist while allowing the surface to dry.

Feeding and Diet

Cataglyphis ants are typically generalist foragers, hunting small insects and collecting nectar and honeydew. In the wild, they are active foragers that search for food items across the desert floor. Their diet likely consists of small insects, nectar, and honeydew from sap-feeding insects.

In captivity, offer a varied diet: sugar water or honey as an energy source, and protein sources like small crickets, mealworms, or fruit flies. Since they are desert ants, they may not accept sugar sources as readily as some other species, observe their preferences. Feed protein 2-3 times per week and keep sugar water available constantly.

Remove uneaten food after 24-48 hours to prevent mold, which is especially important for desert species that are sensitive to excess moisture.

Temperature and Seasonal Care

This species thrives in warm conditions, reflecting its desert habitat. Laboratory colonies were successfully maintained at 31±2°C with a 12:12 light/dark cycle ^[3]. For your colony, aim for 28-32°C in the nest area.

A heating cable placed on one side of the nest creates a temperature gradient, allowing workers to move between warmer and cooler areas as needed. Place the heating on top of the nest, not underneath, to avoid excessive drying of the substrate.

Regarding winter care, the species is found in relatively warm regions (Israel, Egypt, Arabian Peninsula) where winters are mild. While diapause is not well-documented, you should likely provide a cooler period (around 15-18°C) for 2-3 months during winter if the colony shows reduced activity. This mimics the natural seasonal cycle and may help trigger reproductive behavior in spring.

Colony Founding and Reproduction

C. sabulosa follows an independent colony founding (ICF) strategy. Nuptial flights occur in the mornings at the end of April or early May ^[3]. Males fly from their natal nest and land at the entrance to foreign colonies, where copulation occurs near the nest entrance, this is unusual as many ant species mate in mid-air or at specific mating sites.

After mating, freshly mated queens fly away, land, shed their wings, and dig a new nest completely alone. This is classic claustral founding, the queen seals herself in and lives off her stored fat reserves until her first workers emerge. The first workers (nanitics) are typically smaller than normal workers.

Queens are polyandrous, mating with 1-5 males (average 2.3) ^[1]. This multiple mating increases genetic diversity within the colony. Notably, 97% of queens mate more than once ^[3]. The mating system is described as 'multiple-single' (m-s), multiple males per queen, but each queen only mates once per mating event.

Worker Reproduction and Colony Emergency Response

One of the most fascinating aspects of C. sabulosa biology is their backup reproductive system. In queenright colonies (colonies with a healthy queen), workers do not reproduce, none of 152 workers dissected from such colonies had activated ovaries ^[3].

However, if the queen dies or the colony becomes queenless, workers can step in and reproduce. In queenless colonies, workers lay both haploid eggs (which develop into males via arrhenotokous parthenogenesis) and diploid eggs (which develop into females via thelytokous parthenogenesis) ^[3]. This emergency system allows the colony to potentially produce a new queen or at least maintain the colony through male production.

Importantly, new queens (female sexuals) are produced by classical sexual reproduction, not by thelytokous parthenogenesis ^[3]. This means for the colony to truly recover, a new queen must be produced sexually and then mate. The thelytokous parthenogenesis appears to be a conditional strategy used only in queenless situations.

Behavior and Temperament

C. sabulosa workers are active foragers, typical of the Cataglyphis genus. They do not have soldiers (unlike their sibling species C. bombycina) ^[1], so all workers are similar in size with only mild polymorphism (coefficient of variation 0.11) ^[5].

These ants are not particularly aggressive and are suitable for observation. Workers forage individually rather than in groups, searching for food across the substrate. They are diurnal, being most active during the cooler parts of the day in their desert habitat.

Escape risk is moderate, they are not tiny ants but can still climb smooth surfaces. Use standard escape prevention (Fluon on container edges) but you do not need the fine mesh required for tiny species like Pheidole.

The colony structure is stable, queen replacement is uncommon, and all genotyped workers and sexuals are compatible with offspring of the resident queen ^[3]. This suggests the queen is long-lived and colonies are relatively peaceful.
