The science of saving insects: comparing experts’ and non-experts’ understanding of conservation measures

Year: 2026

Type: article

Abstract: The increasing media attention on the decline of insects has made conservation a topic that extends beyond the realm of experts. Although products designed to support insects are widely available, they do not always meet ecological sustainability standards. To effectively conserve insects, it is important to understand the differences in perception between experts and non-experts regarding conservation measures. Therefore, this study compared the perceptions of experts and non-experts regarding the effectiveness of various insect conservation measures and non-experts’ willingness to implement these actions. The study combined interviews with an online survey to gather quantitative ratings and qualitative insights. While most measures were considered effective by both groups, clear differences in perceived effectiveness emerged for some measures. Non-experts overestimated the effectiveness of keeping honeybees, establishing insect hotels and, tentatively, also reducing waste, and underestimated the effectiveness of avoiding outdoor lighting. For some other measures, expert and non-expert ratings tended to vary; however, these differences could not be clearly distinguished from the variability among the experts’ ratings. Additionally, individuals showed a greater willingness to implement measures they believed to be effective. In light of the urgent need for action against insect decline, these results emphasise the importance of improving communication about non-commercial insect conservation efforts aimed at non-experts. It is essential to enhance their knowledge of effective versus ineffective strategies. However, conservation measures should not be evaluated solely based on ecological impacts, as educational and aesthetic benefits can also foster environmental engagement.
