Amazing Cockroach Facts
Run for Your Lives!
The world's largest roach (which lives in South America) is 15cm
long with a 30cm wingspan. Imagine coming across that in your
kitchen! Get your ruler and see how big that would be!
Roaches By the Numbers
Check out these numbers -
6 -- Number of legs on a cockroach
18 -- Number of knees on most cockroaches (at least!)
40-- Number of minutes cockroaches can hold their breath
75 -- Percentage of time that cockroaches spend just resting (how lazy can you get?)
5,000 -- Number of species of cockroaches worldwide
280 million+ -- Years ago that cockroaches are thought to have originated (during the Carboniferous era)
Bad News
Some female cockroaches mate once and are pregnant for the rest
of their lives (bummer).
The Legend of the Headless Cockroach
A cockroach can live a week without its head. The roach only dies
because without a mouth, it can't drink water and dies of
thirst.
Wanna Race?
Cockroaches can run up to 5km in an hour. (Hey, it's no marathon,
but it's not bad.)
Better Check Those Cracks in the Wall
Young cockroaches need only a crack as thin as a 5 cent piece
(about .5mm wide) to crawl into. Adult males can squeeze into a space
of 1.6mm. Pregnant females need the most space to hide: 4.5mm. Get
your ruler and check it out!
Little Hearts
A cockroach heart is nothing but a simple tube with valves. The
tube can pump blood backwards and forwards in the insect. The heart
can even stop moving without harming the roach.
Thirsty Critters
Roaches can live without food for a month, but will only survive
a week without water.
When Cold, Roaches Snuggle
Most species of roaches live in the tropics. But roaches live all
over the world, including the North and South Poles. Pest cockroachs
can withstand temperatures as cold as 0°C, but will die if the
temperature goes much below that. In extremely cold places, however,
they survive by moving in with humans. (Hey, quit hogging the
covers!)
Better Than Air Jordans!
Cockroaches can climb walls because they have a set of little
claws on their feet designed for that very purpose.
Crushed-Roach Bandages?
Crushed cockroaches can be applied to a stinging wound to help
relieve the pain. Try asking your mother for this remedy!
Smell You Later
Sniff, sniff...oh, it's just Uncle Leo. Roaches use their
feelers, or antennae, as noses. Their sense of smell is so great,
they recognize family and friends by their distinctive odours.
Roach Perfume
Female roaches attract male roaches by producing pheromones.
Pheromones are chemicals that make the female roach smell REALLY good
to the males roach.
All right Kids, Beat It!
Some female cockroaches incubate their egg cases in their bodies
until they are ready to hatch. These babies stay with their mothers a
day or two after they are born.
Yuck!
Male cockroaches transfer sperm to females in a "gift-wrapped"
package called a spermatophore. Some males cover the package in a
protein-rich wrapping that the female can eat to obtain nutrients to
raise her young. Delicious!
