Morphological diversity of leaf-cutting ants

Beschreibung

Ants are some of the most abundant and diverse insects on Earth. There are over 14,000 ant species of which 260 grow their food like in human agriculture. These ants, known as the fungus-growing ants do not grow the same crops as humans, but rather a type of fungus. The most specialized group of fungus-growing ants are the leaf-cutting ants, which use freshly cut leaves to grow their fungi. Because of this herbivore behavior, leaf-cutting ants are a damaging crop pest in the Neotropics. However, identifying species of leaf-cutting ants is still challenging because they display an enormous diversity of morphological and biological features. Overall, this prevents us from understanding their biology and effectively controlling their crop damage.

Traditionally, qualitative descriptions of morphological structures have been used to identify leaf-cutting ant species. However, using quantitative measurements of morphological features (morphometrics) to identify distinct species of leaf-cutting ants has yet to be explored. Using tools such as morphometrics is promising to make our species identification more accurate.

Therefore, this project will investigate quantitative morphological differences between species of leaf-cutting ants.

The project addresses the following questions:

  • Are there morphometric differences between species of leaf-cutting ants?
  • Can morphometrics be used to identify species of leaf-cutting ants reliably?

Details zu Projektzeitraum und Durchführung

The project will be carried out at the University of Hohenheim and the Stuttgart Natural History Museum. The main activities in the project are imaging ant specimens and measuring morphological traits. The results of this project will be presented at the Humboldt Reloaded Conference in October 2025.

We are open to developing this project in either German or English. However, a basic proficiency in English is required.
