World Rarest Butterflies



1. The Glasswinged butterfly






Scientific name: Greta Oto


Family: Nymphalidae


Subkingdom: Danainae

The glass winged butterfly can be found in Central America and South America and even Mexico, where they are known as 'espejitos'.

Their wings can grow up to 6.1 cm.

Veins look like they create a web are concentrated throughout  the wings but they don't give them much colour and their typical colour is brown.

When it comes to food these butterflies prefer the nectar of the flowers that are found in the family Asteraceae and Boraginaceae, these flowers help them produce alkaloids that make them taste bad creating this way the perfect defense against predators and also help them to create sex pheromones during the mating season.
Apart from the nectar they also eat birds dropping, which are a great source of amino acids.

and bird droppings, which are a great source to get all the essential amino-acids

Males release pheromones and wait for females to follow the scent and fly towards it to find a mate, also clear winged butterflies congregate in large groups.
