The 5 most important ant subfamilies you need to know
Introduction
Ants, one of the most diverse and ecologically significant groups of insects, are divided into two main evolutionary groups: Poneroids et Formicoids. While Poneroids are the more ancient, solitary hunters, Formicoids are the highly social ants we most commonly encounter in our daily lives. The following table breaks down the subfamilies within the Formicoid group, highlighting their characteristics, the number of species within each subfamily, and some key examples of species. You’ll also notice a few rarer and extinct subfamilies, each contributing to our understanding of ant evolution.
The information presented in this table follows the data from the book of Heather Campbell and Benjamin Blanchard: Ants: A Visual Guide (2023). As such, the species counts and classifications are accurate as of the book’s edition date. This guide serves as a comprehensive resource for understanding the diversity and behaviors of ants, offering detailed insights into their taxonomy and ecological roles. Please note that any subsequent discoveries or updates may not be reflected in this data.

Ant Subfamilies
| Subfamily Name | Number of Species | Main Characteristics |
|---|---|---|
| Formicinae | 3244 | Acid-sprayers, one petiole node, acidopore, common in forests and urban areas. Examples: Camponotus, Formica, Lasius. |
| Myrmicinae | 7075 | Largest group, two petiole segments, often a functional sting, species farm fungus, raise aphids, or go solo. Examples: Solenopsis, Messor, Phéidole. |
| Dolichoderinae | 714 | Chemical warriors, no sting, secrete strong chemicals, one petiole node, often invasive. Examples: Linepithema, Tapinoma, Iridomyrmex. |
| Ponerinae | 1267 | Primitive predators, powerful mandibles, stinger, simple social structure, active hunters. Examples: Odontomachus, Pachycondyla, Harpegnathos. |
| Dorylinae | 749 | Blind, nomadic, with large stingers, no permanent nests, raids in swarms. Examples: Eciton, Dorylus. |
| Agroecamyrmecinae | 2 | Rare, specific ecological niches, limited information. |
| Amblyoponinae | 143 | Ants with large mandibles, relatively solitary, and are found in tropical regions. |
| Aneuretinae | 1 | Extremely rare, small, and poorly studied ants. |
| Apomyrminae | 1 | Known from a single species, specialized ecological role, minimal data. |
| Ectatomminae | 302 | Rare, found in tropical environments, some species exhibit aggressive behaviors. |
| Leptanillinae | 70 | Small, often subterranean, some species are parasitic or specialized hunters. |
| Martialinae | 5 | Rare subfamily, with few known species, information limited. |
| Myrmeciinae | 94 | Known for aggressive behavior, large size, and native to Australia. |
| Paraponerinae | 1 | Extremely rare, species like Paraponera are known for large size and painful stings. |
| Proceratiinae | 163 | Rare, specialized ecological roles, including predation and nest building. |
| Pseudomyrmecinae | 235 | Known for interactions with plants, some species are arboreal. |
| Armaniinae | 12 | Extinct, known only from fossils, poorly understood. |
| Brownnimeciinae | 1 | Extinct, fossil record only. |
| Formiciinae | 6 | Extinct, known from fossils, related to early ant evolution. |
| Haidomyrmecinae | 16 | Extinct, only known from fossils, ancient, with unique morphological traits. |
| Specomyrminae | 12 | Extinct, fossil record only, known for unique physical features. |
| Zigrasimeciinae | 6 | Extinct, only known from fossils, minimal data available. |
Conclusion
In summary, the Formicoid group contains a wide variety of ants, each with unique behaviors, adaptations, and ecological roles. From the acid-spraying Formicinae to the nomadic Dorylinae, these subfamilies demonstrate the incredible diversity within the ant world. While many of these subfamilies are abundant and widespread, others are rarer or extinct, offering a fascinating glimpse into the past and present of these remarkable insects. Whether they farm fungus or conduct massive raids, ants play crucial roles in ecosystems across the globe.
