COSTAL STIGMA Meaning and
Definition
-
Costal stigma refers to a specific characteristic or feature found in certain organisms, particularly in insects and arachnids. The term "costal" refers to the costa, which is a hard, ridge-like structure that runs along the front edge of an insect's wing, providing support and stability. A "stigma" is a darkened or pigmented area on an insect wing that aids in its visual identification. Thus, the costal stigma can be described as a specific pattern or marking located along the costa in the wing of an insect or arachnid.
The costal stigma is often found near the base of the wing, close to the body of the organism. It can vary in shape and size, appearing as a spot, streak, or elongated line. The coloration of a costal stigma may differ from the surrounding wing, frequently being darker or more pigmented.
In entomology, the study of insects, the costal stigma plays a significant role in species identification. Scientists often rely on the presence, absence, shape, and coloration of the costal stigma to distinguish between different insect taxa. By examining this distinctive feature, entomologists can classify and categorize insects into various species, families, or even orders.
Overall, the costal stigma serves as an important diagnostic characteristic that aids in the visual recognition and differentiation of various insect and arachnid species.

Etymology of COSTAL STIGMA
"Costal stigma" is a compound term derived from two distinct etymological sources:
1. Costal: The word "costal" is derived from the Latin word "costa" meaning "rib". In English, it refers to anything related to or located on the ribs or the side of the body.
2. Stigma: The word "stigma" comes from the Greek word "stigma", which originally meant a mark or a sign. In the context of biological anatomy, it refers to a visible or identifiable feature or characteristic.
Therefore, "costal stigma" combines the Latin term for rib ("costal") with the Greek term for a visible feature or characteristic ("stigma") to describe a mark or sign located specifically on the ribs or the side of the body.
