Because One Roach Post Just Isn’t Enough

In my previous post about roaches, I let you know that roaches are helpful to man even if you don’t want to snuggle with them. Now I would like to give you a few fun facts to let you know why they are kinda awesome. In no particular order:

  • Roaches are 340 million years old. That means that they were around even before the dinosaurs.
  • Roaches have amazing little bodies.  The antennae of a cockroach have more than 130 segments each and act as sensory organs for measuring temperature, motion and scent.  Each of their eyes has more than 2,000 compound lenses in addition to a simple eye spot.  Their ears are located in their knee joints.  Their blood is pigment-less and they have no veins or arteries.  Their blood simply flows through their body cavity.
  • Roaches can live several weeks without a head (if proper measures are taken to keep them from bleeding out) because they have two separate and distinct brains.  The first brain is in their head and is the “major” brain.  It deals with complex issues.  The second brain is in the tail and is a simple and “minor” brain.  This brain mostly deals with “RUN!” The nerves of roaches are also 10x faster than ordinary nerves.  This, in conjunction with their minor brain, keeps them several centimeters in front of your foot.
  • Speaking of brains… Roaches are slightly less smart than an octopus.  If you have ever met an octopus, that is saying quite a bit.
  • All of the 5 families of roaches have 4 things in common. 1) They have thick leathery forewings, 2) grasshopper like mouth parts designed for chewing, 3) simple life cycles (no caterpillar or cocoon, 4) and they all make ootheca – hard shelled capsules in which females deposit their eggs.
  • Roaches are in all 50 states and found on every land mass that falls 30 degrees north or south of the Equator.
  • Approximately 40 new species of roach are discovered each year.  The current number of roach species know hovers around 3,500.  Out of those 3,500, about 1.5% are considered domestic pests. For comparison, there are about 4,700 know species of mammals. 
  • There are 5 species of cockroach in the United States – the American, German, Smoky Brown, Oriental, and Brown Banned.  None of these is native to North America.
  • What’s in a name? Cockroach comes from the Greek blattae meaning “domestic pests.” The Romans changed things up slightly when they translated it to mean “pests that flee from light.”  But in fairness, the term included mice and other critters too. Also of note, until WWII, the German cockroach was called the French cockroach.  Hmm.
  • Aggressive behavior in male cockroaches, and I am not making this up, include “stilt walking,” body jerking, biting and kicking (much like the teenager of today).
  • Roaches can stand an obscene amount of radiation.  In humans, 300 rads can cause cellular level change.  400 to 1,000 rads over a 2- to 3-week period is lethal.  Experiments conducted in the 1960s showed adult, German cockroaches could survive a 6,400 rad dose. 
  • And finally, roaches don’t like cucumbers or tomatoes for some reason.  Check that out next time you are at your favorite buffet.

Your Friend: The Roach

A family out for a bite to eat.

A family out for a bite to eat.

Often dogs are credited as “man’s best friend,” but I beg to differ.  I offer you instead the humble roach. 

The usually and immediate reaction to the word “roach” (or the actual specimen) is disgust and panic.  I will fully admit that I don’t love them in our garage and that they give me the creeps when they skitter across the driveway, but I DO enjoy not being waste high in detritus.

Cockroaches are nature’s decomposers and are essential for returning nutrients to the soil.  They take one man’s trash – namely, yours - and turn it into little ecological treasures.

Additionally, roaches make tasty treats for reptiles, amphibians, fish, birds, other insects, and several mammals.  Not surprisingly, humans don’t love them (but have been known to eat them, though not frequently).  This is not because humans don’t like to eat bugs, but rather because of the particular taste of roaches which is similar to ammonia.  If you ever do decide to partake, know that they have three times as much protein as chicken.

Roaches are also good pollinators.  In fact, the first pollinators were beetles, not bees.  They are also the most frequently used speciments in the study of insect behavior, anatomy and physiology.

So in review, if you DON’T like being waste high in debris, but you DO like growing plants and eating, you must love the roach.
