Heliconius erato petiverana roosting gregariously in the insectary in Gamboa

Heliconius erato petiverana roosting gregariously.

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).

I’m in Panama at the moment and wandering down to the insectaries to take photos whenever I can. We collected some H. ismenius on pipeline road and have them in the cage – the males are incredibly active and persistently court this poor female. The female has started laying eggs on P. quadrangularis and P. ambigua.

A mating pair of Heliconius ismenius.  Note the polymorphism in the hindwing – the female has a black band across the centre of the hindwing that is not present in the male.  I’m not really sure whether this represents hybridisation between two geographic forms or a stable polymorphism.  The female was collected already mated from the field and remated in the insectary.

Heliconius charithonia pupal mating behaviour observed by Andrei Sourakov.  This is a little while after the previous photo and the female has now emerged and is extending her wings.  See full description here
