This thesis explores the biology and ecology of insects as an essential component of preschool education, aiming to develop ecological awareness among children. Insects, being the most numerous group of animals on Earth, play a crucial role in maintaining ecosystems and are ideal for introducing fundamental biological and ecological concepts to preschool-aged children. The paper thoroughly examines the biological and ecological aspects of insects, their role in ecosystems, and the ways they can be integrated into educational programs for young children. The study also includes findings from a survey conducted among preschool educators, aimed at assessing their knowledge of insect biology and ecology, as well as their readiness to implement activities focused on introducing these topics to children. The survey results highlight the need for additional education and resources for educators to enhance the quality of educational work in this area. In addition to analyzing existing pedagogical approaches, the thesis presents a case study from a preschool where activities related to insect biology and ecology have been successfully implemented. The conclusions emphasize the importance of early ecological education and ongoing professional development for educators to foster the development of environmentally conscious generations that will value and preserve the natural world.
