This is a photo taken by Patricio Salazar of a Heliconius (Laparus?) doris laying eggs on a P. ambigua in the garden of our house in Gamboa, Panama. The ambigua vine has been growing there for many years, but I have never seen eggs laid on it before. H. doris is an interesting species – it is highly polymorphic for wing pattern. Its taxonomy is also controversial, with molecular data clearly placing it within Heliconius, but morphological data suggesting it is a distinct genus (Laparus). Clearly …

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.

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

Another photo of this persistent H. ismenius male.  The female is raising her abdomen up, which is probably a rejection behaviour – at least it certainly prevents the male from getting to her abdomen from the side, and also probably releases pheromones from scent glands in the female’s abdomen (which may be anti-aphrodisiac).
