Figure 3 is an example of nanoparticulates present in the smoke. Many forest fire cases have been reported to transport micro- and nanosized particles through

Such insects approach ongoing fires and invade the burnt area immediately after a fire. For

• processed centrally (e.g., by the brain) rather than locally in their respective ganglia of origin [2]. It is suggested that smoke-derived odours and IR information converge on descending brain neurons which, in turn, control and direct flight toward the forest fire. Two genera of jewel beetles (family

• , the outbreak of a forest fire is highly unpredictable. Therefore, pyrophilous beetles and bugs must be able to detect fires from distances as large as possible. Furthermore, when flying over a burnt area in search for a place to land, the small insects have to avoid “hot spots” with dangerous surface
