Letenje buba i insekata Prirodni letači su samo insekti, ptice i šišmiši. Prmeri ostalih životinja koje su sposobne su flying fish(riba), leteće veverice, leteće žabe i leteće zmije. Kapacitet za let veruje da su insekti razvili pre nekih 300 miliona godina, i u početku se sastojala od jednostavnog proširenja kutikule od prsnog koša. Uspeh razvoja letenja bio je zbog svoje male veličine. Naravno, nisu svi insekti razvili krila. Neke parazit grupe su izgubili krila kroz evoluciju. Krila insekata se obično sastoje od dva para. To uključuje skakavaca, pčele, ose, vretenca, bube, leptire, moljce i druge. Spoljni par krila obično je prilično težak i nije funkcionalan u letu. Sposobnost za letenje nije određen brojem ili veličinom krila. Neki insekti s velikim krilima, poput Dobsonflies i Antlions, su relativno slabi letači, a pčele i ose sa manjim krila su dobri letači. Velika grupa buba sa samo jednim parom krila, uz male organe za balansiranje poznate kao halteres gde se i drugi par krila mogu razviti. Halteres vibrira sa krila i služi promeni smera.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
