Characteristics associated with insect responses to fire related to the degree of exposure to lethal temperature and stress experienced in the post-fire environment, suitability of post-treatment vegetation as habitat, and ability to rebuild numbers in the site (from survivors and/or colonizers) appear equally useful for explicating insect responsesto other managements such as haying, mowing, and grazing.

It is found that freshwater insect populations have increased overall, perhaps owing to clean water efforts and climate change, and patterns of variation suggest that local-scale drivers are likely responsible for many changes in population trends, providing hope for directed conservation actions.

It is indicated that tallgrass prairie specialist butterflies are not co-evolved with current fire regimes, and declines after preservation will likely continue unless the conservation approach changes to include consideration of individual species’ required resources and management tolerances.

At 106 tallgrass prairies in the midwestern USA, 18,055 individuals of six fritillary species (Lepidoptera: Nymphalidae) were counted and three of four testable fritilla y species significantly d positively correlated in abundance with one or more species of V ola (Vio laceae) (violets).
