摘要

The larva of the bagworm moth Eumeta crameri Westwood uses sticks (either thorns/twigs or both) as materials for building its protective case. During the course of its growth and development, the larva renovates its case three times and at each instance it increases the volume of its case by replacing older sticks by newer and longer ones. In the present study we have measured the length of the longest sticks in addition to larval length and head capsule width soon after the completion of each instance of case renovation to compute Dyar's coefficient. Interestingly, we have observed that increase in the size of the longest stick during successive instances of case renovation follows Dyar's law very closely. Dyar's coefficient showed spectacular constancy when computed by using the data on the length of the longest sticks. What is most surprising is that a stick is an inanimate object, yet the pattern of its increment during the life cycle of the bagworm moth confirms Dyar's principle much in the same way as other biological variables, such as larval length and head capsule width, do. This study uses an inanimate object to compute Dyar's coefficient.
