Raising invertebrates in the classroom is a fascinating teaching method for introducing students to concepts of biology, ecology, and animal behavior. Among the various invertebrates available, ants and stick insects are among the most commonly used species in classroom breeding programs. In this article, we will explore the specific educational advantages of raising ants compared to stick insects and other invertebrates, with a focus on the fluidity of learning.
I. Ant farming: a window into the world of animal societies
Understanding the social structure of ants: Raising ants in the classroom offers a unique opportunity to closely observe their complex social structure. Students can learn how the different castes (workers, soldiers, queens) interact and cooperate to ensure the survival and prosperity of the colony. This experience helps reinforce their understanding of the concepts of cooperation, mutual aid, and communication in the animal kingdom, which are less evident in stick insects and other solitary invertebrates.
Observing ant organization and communication: Ants are highly organized insects that use pheromones to communicate with each other and coordinate their activities. By raising ants in the classroom, students can observe firsthand the different ways ants communicate and organize themselves to accomplish various tasks. This observation promotes learning about the concepts of chemical communication and social behavior, which are less evident in stick insects and other invertebrates.
Understanding the division of labor within the colony: Raising ants in the classroom also allows students to discover how the different castes divide tasks. Worker ants are responsible for foraging, raising larvae, and maintaining the nest, while soldiers defend the colony against intrusions and threats. Queens, for their part, are responsible for perpetuating the colony. This division of labor illustrates concepts such as specialization and efficiency, which are less evident in stick insects and other solitary invertebrates.

II. Ant rearing: an educational tool for studying evolution and adaptation
The diversity of ant species: With over 12,000 species, keeping ants in the classroom offers immense diversity for students. Each species has specific characteristics and lifestyles, providing students with an opportunity to study the evolution and adaptation of ants in different environments and conditions. In comparison, while stick insects also exhibit species diversity, they do not allow for the same wealth of information on evolution and adaptation.
The morphological and behavioral adaptations of ants: Raising ants in the classroom allows students to better understand the morphological and behavioral adaptations that enable these insects to survive and thrive in diverse environments. For example, some ant species have developed strategies for finding food, such as cultivating fungi or raising aphids. In contrast, stick insects and other solitary invertebrates exhibit more limited adaptations, primarily focused on camouflage and defense.
III. The practical advantages of raising ants in the classroom
Ease of care: Ants are relatively easy insects to keep in the classroom. They require little space and can be kept in artificial ant farms designed for easy observation and care. In comparison, stick insects require specific humidity and temperature conditions, as well as more space to allow them to climb and move around.
Sustainability of rearing: Ants are very hardy insects capable of surviving in a variety of conditions. This makes rearing ants in the classroom more sustainable and less likely to fail due to environmental factors. In contrast, stick insects and other invertebrates can be more sensitive to variations in temperature and humidity, which can pose a challenge for rearing them in the classroom.
Reduced environmental impact: Raising ants in the classroom raises awareness among teachers and students about the importance of insects in ecosystems, particularly their role in pollination, decomposition, and biological pest control. This encourages students to adopt environmentally friendly behaviors and better understand the impact of their actions on biodiversity.
Clearly, raising ants in the classroom offers numerous educational advantages compared to keeping stick insects and other invertebrates, particularly regarding the study of social structure, evolution, and adaptation. Furthermore, ant keeping provides practical benefits such as ease of maintenance, sustainability, and a reduced environmental impact. By integrating ant keeping into the curriculum, teachers can offer their students a unique and engaging learning experience while raising their awareness of the importance of insects and biodiversity.
