Strumigenys godmani

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Neotropical region: Costa Rica, Panama, Colombia, Ecuador, French Guiana, Guyana, Venezuela ^[2][3][4]. Found in rainforest floors, cloud forest, and forest edges, from lowlands up to 515 m elevation ^[5][2]. Known nests occur in small rotten logs and under loose bark in damp forest habitats ^[2].
• Colony Type: Unconfirmed, likely monogyne (single queen) based on the holotype queen and the fact that workers are usually found alone ^[2].
• Size & Growth:
  • Queen: ~5.4 mm (total length) ^[6].
  • Worker: 4.5-5.5 mm (total length) ^[1].
  • Colony: Unknown, workers are found singly in the wild, suggesting very small colonies ^[2].
  • Growth: Unknown, likely slow due to specialized predation and low density.
  • Development: No species‑specific data, based on related dacetine ants, development likely takes several weeks under optimal conditions. (Timeline is uncertain, the species has not been studied in captivity.)
• Antkeeping:
  • Temperature: Keep warm and stable, roughly 22-26 °C, typical for lowland tropical forests. Avoid temperatures below 20 °C or above 30 °C. (Inferred from habitat, no experimental data available.)
  • Humidity: Keep the nest substrate consistently moist but not waterlogged. A humidity gradient (drier in one corner, wet in another) works well. Mist the outworld occasionally to maintain ambient moisture.
  • Diapause: No, this tropical species is active year‑round. A slight temperature drop in winter is harmless but not required.
  • Nesting: Use a plaster, Y‑tong (AAC), or soil nest with a moisture chamber. Naturalistic setups with damp soil/peat mix and leaf litter work well. Dark, tight chambers are preferred, cover the nest to reduce light. A test tube setup is fine for founding, but the tube must stay humid.
• Behavior: Strumigenys godmani is a specialized predator with powerful mandibles. It has a functional sting (subfamily Myrmicinae, tribe Attini) but is not aggressive toward keepers unless handled roughly. Workers forage alone, hunting small arthropods. Because of their moderate size (4.5-5.5 mm), escape risk is low, but standard precautions like fluon on container rims are still wise.
• Common Issues: difficulty maintaining a constant supply of live springtails, they are obligate predators and rarely accept dead prey, high humidity requirements, colonies quickly die if the nest dries out, slow colony growth can lead to overfeeding or frustration, unknown founding behavior, wild‑caught queens may fail without special conditions, wild colonies may carry parasites, quarantine new specimens

Housing and Nest Setup

Strumigenys godmani thrives in a setup that mimics its natural habitat, a damp, dark forest floor. Use a container with a plaster or Y‑tong nest that has built‑in water chambers, or a naturalistic setup with a moist soil‑peat mix and a layer of leaf litter on top. Avoid acrylic nests because they cannot hold moisture well. The nest should offer a gradient from wet to dry so the ants can choose their preferred humidity. Keep the entire enclosure dim or dark, these ants are shy and will be more active when covered. For founding, a simple test‑tube setup placed inside a larger container with damp substrate works, but you must replace the water regularly. Provide a small outworld for feeding, just a clean plastic box with a thin layer of damp soil ^[2][5].

Feeding and Diet

Strumigenys godmani is an obligate predator of tiny, soft‑bodied arthropods. Their short, powerful mandibles are built for crushing springtails, booklice, and other micro‑fauna ^[1]. Provide live springtails (e.g., Folsomia candida) at least twice a week. Some individuals may also accept small fruit flies or psocids, but they will ignore sugar water and most dead prey. Do not offer mealworms or crickets, their mandibles cannot handle them. Remove uneaten prey after 24-48 hours to prevent mold. A steady culture of springtails is essential for keeping this species ^[2].

Temperature and Seasonal Care

This Neotropical species comes from warm, humid forests and does not need a winter cooling. Keep the temperature steady between 22 °C and 26 °C, a small heating mat on one side of the nest can create a gentle gradient, but make sure the main nest area stays in that range. Avoid prolonged temperatures below 20 °C. Humidity is far more important than exact temperature: the nest substrate must always feel damp to the touch, but there should never be standing water. If the air is dry, mist the outworld lightly once a day. No diapause is required, the colony will stay active year‑round ^[2].

Behavior and Colony Dynamics

Strumigenys godmani is a quiet, docile ant. Workers forage alone and hunt by slowly exploring the substrate. When disturbed, they usually flee rather than fight. They do have a functional sting (subfamily Myrmicinae) but rarely use it against a keeper. Colonies remain small, in the wild, workers are encountered singly, suggesting that the whole colony has only a couple of dozen to maybe a hundred individuals. Growth is very slow, taking perhaps a year to reach 50 workers. The queen is large (about 5.4 mm) and robust ^[6]. Because the founding method is unconfirmed, captive colonies may be difficult to start from a wild queen. Once established, they are hardy as long as humidity and food are consistent ^[2][1].
