<p>In the last decades, wildfires have become more frequent and are affecting larger areas owing to an increasingly long global fire season. By altering environmental conditions and biomass, they can affect ecosystem function, while also serving as a mechanism that modifies habitat structure. Arthropods have diverse and complex life histories and their responses to fire are generally taxon-specific. The orthopteran species, in particular, have excellent dispersal abilities and are generalist herbivores. We investigated the taxonomic and functional mid-term response to fire (6–10 years after the fire) of orthopteran species in pine plantations from northern Morocco. Pine plantations typically offer suboptimal habitats for orthopterans, due to their dense tree canopy and poorly developed understorey. We expect positive responses to fire as these insects feed on postfire regrowing vegetation. Orthopterans were sampled using pitfall traps and sweep-netting across burned and unburned plots, yielding 151 individuals from 29 species. Our results showed a significant increase in Orthoptera abundance and species richness from unburned to burned plots thanks to the positive response of grassland species. Shifts in the distribution of functional groups between unburned and burned plots were also observed. The positive response of grassland species is due to post-fire changes in vegetation structure which creates new ecological sources, providing these species with new opportunities for nesting, foraging and thermoregulation. </p><p><b>Implications for insect conservation: </b> Our findings suggest that appropriate management of pine plantations can enhance orthopteran taxonomic and functional diversity, particularly for species sensitive to dense tree canopies.</p>
