B\u00f6cekler, d\u00fcnyada en \u00e7ok \u00e7e\u015fitlili\u011fe (t\u00fcr say\u0131s\u0131na) sahip olan hayvanlar olarak da bilinmektedirler; 800 binin uzerinde t\u00fcr \u015fu ana kadar tan\u0131mlanm\u0131\u015f olmakla birlikte halihaz\u0131rda bu listeye yeni t\u00fcrler eklenmektedir. Kutuplardan okyanuslara kadar hemen her ekosistemde ayakta kalmay\u0131 ba\u015farabilmi\u015f canl\u0131lard\u0131r. Canl\u0131lar aleminin belki de en kalabal\u0131k s\u0131n\u0131f\u0131d\u0131r. Yakla\u015f\u0131k olarak 30’un \u00fczerinde tak\u0131m i\u00e7erir. Tan\u0131mlanm\u0131\u015f olan hayvanlar\u0131n yakla\u015f\u0131k 4\/5’i b\u00f6ceklerdir.<\/p>\n
V\u00fccutlar\u0131 cephalo (ba\u015f), thorax (g\u00f6\u011f\u00fcs) ve abdomen (kuyruk) olmak \u00fczere 3 b\u00f6l\u00fcmden olu\u015fur. Baz\u0131 gruplarda bu v\u00fccut b\u00f6l\u00fcmlerinde kayna\u015fmalar g\u00f6r\u00fclebilir. Ba\u015f b\u00f6lgesinde bir \u00e7ift anten ve bir \u00e7ift bile\u015fik g\u00f6z bulunur. S\u0131n\u0131f \u00f6zelli\u011fi olarak g\u00f6\u011f\u00fcsleri 3 segmentlidir ve her segmentten bir \u00e7ift bacak \u00e7\u0131kar. \u00c7o\u011funda 2. ve 3. g\u00f6\u011f\u00fcs segmentlerinden birer \u00e7ift kanat \u00e7\u0131kar. Hayvanlar aleminde “u\u00e7ma” ilk defa bu grupta ortaya \u00e7\u0131km\u0131\u015ft\u0131r, ancak b\u00f6ceklerin kanatlar\u0131, ku\u015flar\u0131n kanatlar\u0131ndan farkl\u0131 yap\u0131dad\u0131r. Abdomen (g\u00f6\u011f\u00fcs) 11 segmentlidir ve hi\u00e7bir segmentte \u00fcye bulunmaz. Son segmentlerde yap\u0131sal de\u011fi\u015fiklikler sonucu olu\u015fmu\u015f kavu\u015fma organ\u0131, cercus uzant\u0131lar\u0131 veya yumurta yerle\u015ftirme borusu gibi yap\u0131lar g\u00f6r\u00fclebilir.<\/p>\n
D\u0131\u015f iskelet bulunur. B\u00fcy\u00fcme esnas\u0131nda d\u0131\u015f iskeletin neden oldu\u011fu k\u0131s\u0131tlama, deri de\u011fi\u015fimi ile telafi edilir. V\u00fccutlar\u0131nda sadece \u00e7izgili kas bulunur. Solunum trake sistemiyledir. A\u00e7\u0131k dola\u015f\u0131m sistemi g\u00f6r\u00fcl\u00fcr. V\u00fccutta dola\u015fan solunum s\u0131v\u0131s\u0131 “hemolenf” ad\u0131n\u0131 al\u0131r ve \u00e7o\u011funlukla renksiz, bazen de soluk ye\u015fil-sar\u0131 renktedir. V\u00fccutlar\u0131 bez bak\u0131m\u0131ndan zengindir. \u00c7ekici veya itici koku, mum, zehir, ipek, ya\u011f, t\u00fck\u00fcr\u00fck, antikoag\u00fclan madde gibi bir\u00e7ok maddeyi salg\u0131lamak \u00fczere \u00f6zelle\u015fmi\u015f \u00e7ok say\u0131da bez ta\u015f\u0131rlar. Duyu organlar\u0131 ve sinir sistemleri iyi geli\u015fmi\u015ftir. Bir\u00e7ok grupta, \u00f6zel g\u00f6revleri olan duyu organlar\u0131na rastlan\u0131r (yeri geldik\u00e7e a\u00e7\u0131klanacakt\u0131r). Avlanmak veya avc\u0131lar\u0131ndan korunmak i\u00e7in son derece ba\u015far\u0131l\u0131 uyumlar kazanm\u0131\u015flard\u0131r. Renklenmeleri b\u00fcy\u00fck \u00e7e\u015fitlilik g\u00f6sterir. Baz\u0131lar\u0131nda \u0131\u015f\u0131k \u00e7\u0131karma \u00f6zelli\u011fi g\u00f6r\u00fcl\u00fcr.<\/p>\n
Kural olarak yumurta ile \u00e7o\u011fal\u0131rlar ve geli\u015fmelerinde \u00e7o\u011funlukla bir metamorfoz g\u00f6r\u00fcl\u00fcr.<\/p>\n
Baz\u0131 gruplarda koloni h\u00e2linde sosyal ya\u015fam \u00f6rnekleri g\u00f6r\u00fcl\u00fcr.
