Collections of selected orthopteroids, neuropterans, coleopterans, and hymenopterans were made before and after flood and fire disturbances in the Big Thicket National Preserve, Texas in 2017–2019. Comparisons of samples suggest that different insect groups vary in their responses to these disturbances. Antlions decreased in number substantially after flooding, but grasshoppers and beetles of the families Scarabidae and Cerambycidae did not. After a prescribed burn, the wasp genus Pluto increased significantly, but grasshoppers and mantises did not. Possible explanations for observed results are discussed.
