Fun with Bugs

Cockroaches can live for several weeks after having their heads chopped off.

The roach brain does not control this breathing and blood does not carry oxygen throughout the body. These cold blooded vermin breathe through spiracles, or little holes in each body segment.  These spiracles pipe air directly to tissues. And it is not just the body that can survive decapitation; the lonely head can thrive, too, waving its antennae back and forth for several hours until it runs out of steam, if given nutrients and refrigerated, a roach head can last even longer.

Cicadas love song

Cicada

In the south we are blessed with the love songs of the male Cicada, as he sings his song in hopes to attract a mate. The sound of the cicada love song can be deafening. In fact, it’s the loudest song known in the insect world. Some species of cicadas register over 100 decibels when singing.  Their song is technically loud enough to cause permanent hearing loss in humans, should the cicada sing just outside the listener’s ear (unlikely). 

Mosquitoes

MosquitoeOne of our favorites,  are very widespread, occurring in all regions of the world except for Antarctica.   Mosquito-borne diseases include:  West Nile virus, yellow fever, dengue fever and malaria to name a few. Some authorities argue accordingly that mosquitoes are the most dangerous animals on Earth. Mosquitoes have killed more humans than all the wars in history.
