Early in the day
males perch high in the canopy and chase each other rapidly in wide
circles around the tree tops.
In late morning
they descend to the understorey, and in the afternoon are
sometimes encountered in the vicinity of streams and waterfalls. In
common with the males of numerous other butterflies of all families,
they imbibe mineralised moisture in order to procure vital salts.
However whereas most species choose to imbibe from patches of damp
ground, Pereute males have the peculiar
habit of sitting in precarious positions, sometimes partially
submerged, among pebbles in the middle of fast flowing shallow
streams. I have come across this phenomenon numerous times with
various Pereute species in Costa Rica,
Venezuela, Ecuador and Peru, but can find no logical explanation.
Pereute males are exceedingly placid. No amount of molestation
will cause them to fly, but conversely when encountered at rest on
foliage on narrow forest trails, they are extremely alert and very
difficult to approach.
Females are normally only seen when
visiting Fuchsia or
Eupatorium for nectar.
