Butterfly can see?

Question

Can butterflies see Humans?

Answer 1

Butterflies can see. Far better than you would think. They have multi faceted compound eyes that cover cover a wider field of view than humans. They also see in different light spectrums which allow them to see the flowers they like to feed on best. Being nectar eaters, the butterflies need to feed on plants that suit them.
As the caterpillars feed on vegetation, the butterflies tend to feed on those plants flowers as well. This is a generalisation as some caterepillars actually are carnivores and live in ants nests or require the ants to look after them. The butterflies, if they do feed, pick flowers by sight, which suit the feeding need.
The same, also goes for moths. They are particular about what they feed on and quite often, moths and butterflies will only use one plant as a feeding source. This has developed because that the butterfly or moth is the only source of fertilisation of the flower. Cacti are the classic example, they flower on a few nights when the moths are about.
The Monarch butterfly, as a caterpillar, feeds on milkweed plants, plants that produce a white milk. This causes the caterpillar to be inedible. This would mean that the butterfly would be able see the plant that it was going to lay its eggs on.
If you get the chance, go to a butterly house. This is a place where they breed butterflies. To feed the butterflies, they use plastic flowers and each species of butterfly will go to the plastic flower of its preferred colour to feed on the sugary food that is provided for them.
