The underwing pattern is highly cryptic.It is conceivable that the eye pattern is a generalized form of mimicry.It is known that many small animals hesitate to go near patterns resembling eyes with a light-colored iris and a large pupil, which matches the appearance of the eyes of many predators that hunt by sight.
A floral diagram is a graphic representation of the structure of a flower. It shows the number of floral organs, their arrangement and fusion. Different parts of the flower are represented by their respective symbols. Floral diagrams are useful for flower identification or can help in understanding angiosperm evolution.
This neotropical butterfly is found in Central and South America, including the Cerrado which is a vast tropical savanna in Brazil. [5] Other locations include Mexico [2] and Venezuela. [6] Ancestors of the Morpho menelaus butterfly may have been distributed in the Andean regions. [4] Morpho menelaus is one of the six species of Morpho in Costa ...
