Butterflies have two different types of eyes, single and compound. The one pair of simple eyes, ocelli, are single chambered and are primarily for determining light brightness. They are unable to focus on an individual object. The compound eyes are multifaceted and are used for their main eye sight. The light comes through one facet and is received by one rhabdom, similar to human retinas. Butterflies are able to see light wavelengths from 254 to 600 nm, this includes ultraviolet light, a light that we are unable to see. People can see.
Butterflies have a siphoning-sucking mouthpart structure, a proboscis. It is similar to a long tube and coils up underneath the head of the butterfly. In the center of the proboscis there is a food tube through which the nectar is siphoned. Along two sides of the food canal, there are small muscles that control the coiling and uncoiling of the proboscis.
Butterflies have one pair of segmented antennae. The basic shape is clubbed, meaning the segments increase in size as it gets further away from the head.
ADAPTATION OF BUTTERFLY
Butterflies adapt relatively quickly, making them an ideal subject for studies about evolution. Scientists examine how butterflies develop different mate preferences, and they argue that this leads to adaptations that go much deeper than just color variation.
The wing colors and patterns of butterflies are one of their most visible adaptations. Some butterflies have wing patterns that allow them to blend into their surroundings, while others have colorings that make predators believe they are poisonous. Still other butterflies have wing patterns that look like eyes, making them appear larger and scarier to enemies.
Although many children are told that touching a butterfly's wings ruins them and makes it impossible for the butterfly to fly, which is not true. Butterflies have adapted to have a clear membrane underneath their wings, and this protects the integrity of their wings.
As butterflies deal with rising temperatures, many of them adapt by seeking shelter in cooler habitats. Others expand their range into cooler areas or higher altitudes. However, only a small portion of butterflies are making this adjustment. Scientists in Spain have discovered that for every 1 degree Celsius increase in temperature, approximately 1 percent of the butterflies hide in cooler areas.
