For this assignment I chose The Shocking Sex Secrets of Insects by Dr. Zuk is an evolutionary biologist at the University of Minnesota and author of several books concerning insects and evolution. This article is important because of the discovery of fossilized insects that were mating 165 million years ago. This could give researchers information on how the reproductive behaviors and anatomy of insects have evolved. Dr. Zuk discusses the mating behaviors of damselflies, crickets, water striders, and cockroaches. Each of these insects mating behavior and genitalia are unique. Just as unique is the way the dominate male, or female in some cases, uses their genitals to ensure reproduction of the strongest insect is achieved. .
Damselflies are members of the Odonata order and their scientific name is zygoptera which means paired wings. Based on the article Dr. Zuk refers to damselflies, however the actual genus is not identified. Based upon my research the number of damselfly genera is too great to list. A common damselfly which is native to the area where I live is the Ebony Jewelwing which belongs to the genus Calopteryx (Lung and Sommer, 2001).
According to Dr. Zuk "The elaboration of insects' genitalia also has a more diabolical side. A female damselfly may mate with more than one partner, but from each male's perspective, the more of her eggs he can keep from rivals and fertilize himself, the better. The spines and scoops on his penis serve to remove the prior male's sperm so he can replace it with his own. Based upon the information covered in ENT 202, Module 10, Page 4 Damselflies are members of the Odonata order which require direct sperm transfer in order to reproduce. Male damselflies are also equipped with an appendage that can remove rival damselflies sperm from the female in order to insert his own. The biological information in Dr. Zuk's article appears to coincide with the information covered in class during week 5.
