The Greta Oto or the glass-winged butterfly, is a butterfly
that has attractive transparent wings with an opaque lining along the edges. It
is mainly been found in Mexico and along the panama Islands. One of the
surprises it has for people who study the lives of these organisms is that
there are some debates about where it lays its eggs. Some have pointed to some
grounds around the places where it is found. But evidence has pointed to the
fact that it lays its eggs on the leaves of plants. A fully developed adult can
easily be seen in the groups when time comes for migration. They have been
known to migrate for long distances as compared to other species of
butterflies.
When the glass winged butterfly lays eggs, the caterpillar
that later develops from the larva is considered to be toxic. For this reason,
this caterpillar is not eaten by predators. In fact, even a fully grown
butterfly is considered to be toxic
and is not eaten too. This is mainly attributed to its
feeding on toxic vegetation by the male butterflies. These males use the
chemicals from such plants to develop features that attract females. In fact,
this is one feature which has helped in marking its survival among a series
of possible predators.
The wings of a glass winged butterfly have been estimated to
be between 56 milimeters to 61 millimeters. The body of this amazing butterfly
is also something intriguing enough to capture even the attention of the
busiest individual. First, it has those elegant translucent wings with edges
ranging in color from brown to red or generally opaque. But the body is
completely dark in color. The feature of having colorless wings seems to have
been so distinctive that its Spanish name is espijitos which, when translated,
in English literally means little mirrors. Perhaps that is why even in many
other languages that have attempted to give is unique names have all ended up
having something to say about the main feature.
