Resumo

Fire is one of the main disturbance agents globally and one of the main threats on the Brazilian cerrado (Neotropical savanna), acting as environmental filter for species selection. Individuals of Morpho helenor achillides (C. Felder and R. Felder, 1867) and M. menelaus coeruleus (Perry, 1810) were captured weekly using entomological nets and fruit-baited traps over a 36-mo period (from May 2005 to April 2008). The present study analyzed the impact of a fire event in both the above species, showing that they present different responses to this disturbance. Morpho helenorwas persistent as adults during the dry season, which could fly away from the flames to neighbor unburned areas and return after dry-season bushfires. Conversely, Morpho menelaus persists only as caterpillars during the dry season, which are unable to escape from the flames resulting in high impacts on local population (the species was not captured up to the end of this study). In addition, based on host plant species reported in the literature, we assigned a broader host plant range to M. helenor, suggesting that a generalist diet could help in the maintenance of individuals during the dry season, as they have more options to breed all year round. A better understanding of the temporal dynamics of adult and immature stages could help predict the amplitude of the impacts of dry season fire events on insects, especially when preventive fires are strategically used inside protected areas.
