Count the segments on the ventral surface of the male and female abdomen. The number of visible segments is higher in the male than the female. Also the females posterior abdomen is broader and more rounded than the male.
Do cockroaches sleep?
Yes, cockroaches do sleep, if you define it that way. Cockroaches have activity rhythms, i.e. regular times in the day when they are quiet and hide away from the rest of the world as well as wakeful times when they are active, seeking food, water and a mate.
Are cockroaches clean?
Cockroaches clean themselves very scrupulously in order that their sensory bristles on their body walls and limbs are ready to sense any hint of water, food, a mate or an enemy. Thirst, hunger, sex and safety rule the cockroach life. However, the cockroach GI tract can harbor all the diseases that are being passed around in the house or neighborhood. They are omnivorous and thus would just as likely eat a dead mouse or a bit of fallen cheese or nibble on your house plant. They often defecate near or on the food they eat so they are likely to pass the organisms in their GI tract to the food they are eating and the surfaces they walk and defecate on.
Can a cockroach live without it's head?
Yes, a cockroach could live a long time, perhaps a month, without its head.
Can a female cockroach without a head, mate and bear offspring?
A female carrying fertilized eggs could be headless and the eggs she carries could hatch.
Can baby cockroaches hatch on your tongue?
The cockroach egg is huge. Most eggs are 2 mm long and are closely packed side by side and 2 by 2 like franks in a dozen package. They do not survive outside of the oothecae or egg case, which contains 12-40 of the eggs, and cannot be associated with the lickable surface of an envelope in any way such that they were transferred into a paper cut tongue. You just have to sit back and laugh at the gullible nature of the CNN producer/director who did not have enough biology in his education to know when he/she was out of her depth and needed to consult with someone who knew better.
Are cockroaches good for anything?
Cockroaches as a group are part of the worldwide food web. They are omnivore scavengers which clean up our environment and help recycle the organic litter that would accumulate if it were not decomposed by organisms which include cockroaches. Furthermore they serve as food for small mammals, birds, amphibians and lizards. There are over 3000 species of cockroaches and only 10 species are on the World Health Organization list of human pests. The other 3000 species are welcome members of the biodiversity on this planet.
What color blood do cockroaches have?
Cockroach female adult blood is occasionally orange. All other cockroach blood is colorless.
Do cockroaches feel emotions?
Emotion is not usually associated with insect or cockroach behavior. The cold and unmoving surfaces of the insect exoskeleton do not allow for movement of surface muscles and skin that one can interpret as a smile or other facial emotion. Insects react to environmental cues with reflexes that we usually do not interpret as emotion.
How many baby cockroaches can one female produce?
The American cockroach produces 1 ootheca per 2.5-3 days with each ootheca bearing about 12 offspring. The number of ootheca in the adult life of an American roach is probably somewhere in the literature. The egg cases start being less frequent as the female gets older and some of the ovarioles become inactive such that an ootheca might only contain 6-8 eggs in later life. I presume an adult female might continue the output for 6 months (although that is a guess) so resulting in 60 ootheca x 12 = 720 offspring. The variance about this average might be quite high so I would not be surprised by actual counts of females producing 500-1400 offspring in her lifetime.
