Answer:
The bright color of butterflies is a discouraging factor for its prey
Step-by-step explanation:
Butterflies and caterpillars are easily visible to its prey but still they do not eat any of them. This can be because of two factors –
a) The bright color of these organisms might be a factor that makes them uninteresting (intending to be tasteless etc.) for their prey
b) The bright color might be a signal to the bird indicating in advance of any harm associated with the butterflies/caterpillar feeding.
Hence , instead the Monarch butterflies have brightly colored orange wings with black patterns on them, making them easily visible to birds, the birds rarely eat the monarchs
