Bioacoustics of Conocephalus (Anisoptera) guartela

Comments This species is polymorphic; the individuals can be mesopterous or macropterous, independent of the sex. This also occurs in C . ( A .) saltator (see Chamorro-Rengifo et al . 2018 ). Sex association was done by observing copulation: the holotype was collected copulating with the female of same data; when rearing, the female started copulation with another male, which is macropterous. Furthermore, the bioacoustics of mesopterous and macropterous individuals have a few variations, as detailed below. In vivo , some individuals had colours that varied from green to brownish, with legs usually brown, and the apex of abdomen always lighter than the general colouration, usually orangish. Individuals of this species were quite difficult to collect, even if the population seems to be large in the driest areas of the GSP; they were very active, and when the vegetation was minimally disturbed, they quickly jumped or flew to the ground, hiding in the dense grass leaves. Specimens were collected in the driest areas of Cerrado formations; they were observed feeding on seeds of grasses, such as Steinchisma and Melinis (Poaceae) . Females were observed laying eggs in stalks of grasses of these genera. The Cerrado formations seem to be quite important to the conservation of this species, especially given that these areas occupy mainly the highest portions of the park. If we note that there are only two Cerrado formations inside Paraná parks, the preserved area that this species inhabits is extremely restricted.
