This amazing footage of an H. erato pupating is at 10X normal speed. This transformation happens pretty fast in real time.

Heliconius melpomene aglaope processing a pollen load.  Adults may spend several hours processing pollen, producing saliva which is mixed with the pollen to release amino acids and then ingested.  The large grains of white pollen in the photo are from Psiguria warcewiczii.

A Heliconius erato petiverana female roosting, hanging from the wings of another.  Note the characteristic roosting posture of females (both individuals here are female), with their hindwings covering the forewing band.

Heliconius erato petiverana roosing gregariously in the insectary in Gamboa.  Individuals coming in to roost spend several minutes ‘fanning’ the butterflies already hanging up, often dislodging them from the perch.  The reason for this social behaviour is not really well understood.

Normally, a natural background is nice, but artificial feeders are quite colourful…. Heliconius erato erato
