This blog will attempt to prsenter large groups of animals with emphasis on their biology, phylognie their ecology etc.. Animals n'tant reprsents not only by vertebrates and mammals sometimes you come across "strange" animals. In fact, the only vertebrates reprsentent 5% of animals ... Imagine the surprise that it remains in the remaining 95%! Enjoy your visit!

WE LIVE IN RE THE beetles! The beetles-colo = Case, sleeve and ptre = wing are very friendly insects whose wing SECOND pair protects the First as a tui. This first pair of wings is called lytre (elytr = envelope) is sclrifie is (that is to say cured). the lytres addition to their role as protectors provide a surface lift in flight, which sometimes gives the impression of flying plane in these insects. These are the ladybugs, beetles, beetles, stag beetles, beetles, grubs, beetles, balanins, dung, ctoines, glowworms etc.. the list is long ... - But if there has something impressive, what do I say? terrifying in beetles is their DIVERSITY! . Indeed, there by Most recent internship estimates, more than 300,000 species of beetles! And this number could rise because still discovers every day! As a guide we expect mammals in 5000 is 60 times less! and all vertebrates has 50,000 species is 6 times less! The second largest order of insects is that of diptres with "only" 150,000 species! Biologist how to relieve chafing John Haldane ame rpondu the question "What is your studies of the nature you have rvl the nature of God?" "The Creator, if He exists, has a passion for dmesure beetles!" . The beetles reprsentent 16% of living species rpertoris (I did not say animal!) Which is standard for a group! -This raises the question of the formation of species. I do not know why this group was so russis and why there are so many species. What is espce? how to relieve chafing For very sexual reproduction are two living things that can reproduce them and give fertile offspring. the theory of evolution tells us that species are never clearly dlimites in time and in space. This says a given time we can clearly some Sparer. The formation of species is called spciation: Girl species will give two or more. Typically we talk about spciation allopatric (Patrick Allo? Could I speak to your wife?) Of all = other = pre and Patrique, country, location. The original population is sparegographiquement two and two populations diverge until no longer be able to cross if there is new contact. No doubt that there are not enough places on earth to Sparer all species of beetles! Another type of spciation is very tudie in insects: the sympatric spciation (sym = same, so it is "in the same place spciation "). here, no barrire geographical: the species then form that people are shuffled. This is natural selection and sexual selections used engine for subpopulations of the populations of origin and sparent differ enough that they form two distinct species then. Briefly, question? appointment in the comments! -Knowing this diversity in coloptre, something of hit you ... Their homogeneity! Indeed, the number of species has beautiful mind-boggling be a coloptre is not well diffrent another coloptre ... This also may seem surprising molluscs (spciale ddicace to my darlings) reprsents "only" by 100,000 species have a well Suprieure morphological diversity. This is partly because molluscs appeared there much longer. Having said this "monotony" (because I exagre even when there is the diversity among beetles) seems amazing despite all compared to the number of species. -The "montage" picture represents, from top to bottom, the three stages of ladybirds: larva, nymph, imago.
The beetles are:-bilaterian-Protostomes-Cuticulates (they have a carapace)-Ecdysozoans (they lose their cuticle regularly by molting as they grow)-Panarthropodes how to relieve chafing (segments animals
