Dolichoderus shattucki

Dolichoderus shattucki

Dolichoderus shattucki is a Neotropical ant species native to the forests of Panama, Colombia, and Ecuador. Workers are medium-sized with a distinctive appearance featuring very long maxillary palpi, eyes that protrude beyond the head margin, and well-developed spines on the pronotum, mesonotum, propodeum, and petiole. The entire body is covered with erect to suberect hairs, giving them a somewhat bristly look ^[1]. This species is an indicator of minimally disturbed forest ecosystems, found primarily in mature forest habitats like Río Azul ^[2][1].

These ants are part of the Dolichoderinae subfamily, which means they lack a stinger but can defend themselves by spraying formic acid. They are arboreal or semi-arboreal nesters in the wild, typically inhabiting rotting wood in humid forest environments. The species was described by Mackay in 1993 from Panama specimens ^[1].

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Neotropical forests of Panama, Colombia (Nariño, Valle del Cauca), and Ecuador (Pichincha province). Found in mature forest habitats and indicator species of minimally disturbed forest areas ^[2][1][3].
• Colony Type: Colony structure is unconfirmed. Based on typical Dolichoderus patterns, likely single-queen (monogyne) colonies, though this has not been directly documented for this species.
• Size & Growth:
  • Queen: Estimated 6-8mm based on genus patterns, no specific measurements available
  • Worker: Estimated 4-6mm based on genus patterns, no specific measurements available
  • Colony: Likely moderate colony size (several hundred workers) based on typical Dolichoderus patterns, unconfirmed for this species
  • Growth: Moderate, estimated based on genus patterns
  • Development: Estimated 6-10 weeks at optimal temperature based on related Dolichoderus species (Timeline is estimated, no direct development data available for this species. Temperature dependency follows typical Neotropical ant patterns.)
• Antkeeping:
  • Temperature: Keep at 24-28°C. Being a Neotropical species from humid forest habitats, they prefer warm and stable conditions. A heating cable on one side of the nest can create a gentle gradient
  • Humidity: High humidity required, think damp forest floor. Keep nest substrate consistently moist but not waterlogged. Provide a water tube for drinking access. Avoid drying out the nest
  • Diapause: Likely minimal or no true diapause given their Neotropical origin. May show reduced activity during cooler months but probably don't need a full hibernation. More research needed on their seasonal requirements.
  • Nesting: Based on typical Dolichoderus behavior, they prefer nesting in rotting wood or arboreal cavities. In captivity, a Y-tong (AAC) nest or plaster nest with good moisture retention works well. Provide damp substrate and avoid dry conditions.
• Behavior: Generally calm temperament compared to some other ant genera. They are not aggressive but will defend their nest if threatened. Workers forage actively and can spray formic acid as a defense mechanism. Escape risk is moderate, use standard barrier methods but they are not particularly escape-prone like some tiny species. They are primarily arboreal foragers in the wild but will adapt to ground-level foraging in captivity.
• Common Issues: high humidity maintenance is critical, drying out causes colony decline, limited availability of wild-caught queens makes starting colonies difficult, slow growth compared to faster-raising species may frustrate beginners, wild-caught colonies may have parasites that are difficult to detect, temperature drops below 22°C can slow or stop brood development

Housing and Nest Setup

Dolichoderus shattucki does well in nests that retain moisture well. A Y-tong (AAC) formicarium or a plaster nest works nicely for this species. The key is keeping the nest substrate consistently damp without creating standing water. Place a water tube connected to the nest so workers can drink, they will readily use it. Because they come from humid forest environments, avoid dry conditions entirely. Some keepers add a layer of damp soil or coco fiber in part of the nest to help maintain humidity. A test tube setup can work for founding colonies, but monitor moisture levels carefully as test tubes dry out faster than larger nests. ^[1][2]

Feeding and Diet

Based on typical Dolichoderus feeding patterns, these ants are omnivorous and will accept both sugar sources and protein. Offer sugar water, honey, or diluted maple syrup as a constant sugar source. For protein, provide small insects like fruit flies, small mealworms, or cricket pieces. They are not specialized predators so standard ant feeds work well. Feed protein 2-3 times per week depending on colony size, and keep sugar water available at all times. Remove uneaten prey after 24-48 hours to prevent mold issues.

Temperature and Seasonal Care

As a Neotropical species from Panama, Colombia, and Ecuador, Dolichoderus shattucki prefers warm conditions. Keep the nest area between 24-28°C for optimal brood development. A slight temperature gradient allows workers to choose their preferred zone. During cooler months, they may show reduced activity but probably don't require a full hibernation period like temperate species. If your room temperature stays above 22°C year-round, that should work fine. Avoid temperatures below 20°C for extended periods as this can stress the colony and slow or stop brood development. ^[3][1]

Behavior and Colony Dynamics

Workers of Dolichoderus shattucki are active foragers with a generally calm disposition. They lack a stinger but can spray formic acid as defense, this is harmless to humans in small amounts but can be irritating. Colonies grow at a moderate pace compared to faster-raising species like some Formicinae. The first workers (nanitics) may be smaller than mature workers. Once established, colonies can reach several hundred workers over time. They are not aggressive toward keepers and rarely bite. Standard escape prevention measures work well, they are not particularly escape-prone like very small species. ^[1]
