Editing Convergent evolution (section)

===Insect mouthparts===
Insect mouthparts show many examples of convergent evolution. The mouthparts of different insect groups consist of a set of [[homology (biology)|homologous]] organs, specialised for the dietary intake of that insect group. Convergent evolution of many groups of insects led from original biting-chewing mouthparts to different, more specialised, derived function types. These include, for example, the [[proboscis]] of flower-visiting insects such as [[bee]]s and [[flower beetle]]s,<ref name="Krenn-2005">{{cite journal |last1=Krenn |first1=Harald W. |last2=Plant |first2=John D. |last3=Szucsich |first3=Nikolaus U. |year=2005 |title=Mouthparts of flower-visiting insects |journal=Arthropod Structure & Development |volume=34 |issue=1 |pages=1–40 |doi=10.1016/j.asd.2004.10.002}}</ref><ref name="Krenn-2011">{{cite journal |last1=Bauder |first1=Julia A.S. |last2=Lieskonig |first2=Nora R. |last3=Krenn |first3=Harald W. |year=2011 |title=The extremely long-tongued Neotropical butterfly Eurybia lycisca (Riodinidae): Proboscis morphology and flower handling |journal=Arthropod Structure & Development |volume=40 |issue=2 |pages=122–7 |doi=10.1016/j.asd.2010.11.002|pmid=21115131 |pmc=3062012 |bibcode=2011ArtSD..40..122B }}</ref><ref name="Krenn-2012-1">{{cite journal |last1=Wilhelmi |first1=Andreas P. |last2=Krenn |first2=Harald W. |year=2012 |title=Elongated mouthparts of nectar-feeding Meloidae (Coleoptera) |journal=Zoomorphology |volume=131 |issue=4 |pages=325–37 |doi=10.1007/s00435-012-0162-3|s2cid=9194699 }}</ref> or the biting-sucking mouthparts of blood-sucking insects such as [[flea]]s and [[mosquito]]s.
