Insect populations, particularly those of the Coccinellidae (lady beetles), which are essential to the balance of ecosystems, are greatly impacted by climate change. For sustainable agriculture and conservation initiatives, it is essential to comprehend how climate influences beetle diversity and distribution. Investigating the climate factors influencing Coccinellidae populations in Faisalabad, Punjab, Pakistan, is the goal of this study. Three natural zones—wetlands, urban residential areas, and agricultural fields—were sampled using a stratified sampling technique. Visual observations, pan traps, sweep nets, and transect walks were among the sampling techniques used. Environmental factors that were documented included the existence of flowers, the composition of the land, and the application of pesticides. Taxonomic keys were used to identify the collected beetle specimens, and species richness, dominance metrics, and diversity indices including the Shannon Diversity Index were used for analysis. The monsoon season (June–July) has the largest beetle diversity, according to the results, because of the increased humidity and floral abundance. In contrast, the winter months have lower diversity because of insect slumber. Ground beetles, or the Carabidae, are the most prevalent family and exhibit environmental flexibility. Because of habitat fragmentation and chemical exposure, beetle populations are higher in agricultural regions with a variety of plant life than in urban and industrial locations. The two main factors controlling beetle abundance—temperature and humidity—have an impact on both reproduction and survival. The significance of local environmental conditions is highlighted by variations in beetle populations across various land-use patterns. Significant variations in the distribution of beetles among the places under study are confirmed by statistical analysis. Additionally, the study shows a relationship between beetle abundance and seasonal fluctuations, highlighting the part that climate plays in shaping insect population. In order to support beetle populations and preserve ecological stability, this research emphasizes the necessity of habitat conservation, sustainable farming methods, and public awareness campaigns.
