Cubital index

Cubital index is the ratio of two of the wing vein segments of honeybees.

The pattern of the veins of the fore wings is specific for each breed of bees.

The cubital index is consistent for a given race of bee.

It can be used to distinguish between similar populations of honeybees and to determine degrees of hybridization.

To obtain reliable average results, at least 100 bee fore wings have to be analyzed.
