These dragonflies are usually black or dark brown with areas of metallic green or yellow, and most of them have large, emerald-green eyes. The [larva](/source/larva)e are black, hairy-looking, and usually [semiaquatic](/source/semiaquatic_insect). This family include species called "baskettails", "emeralds", "sundragons", "shadowdragons", and "boghaunters". They are not uncommon and are found nearly worldwide, but some individual species are quite rare. [Hine's emerald dragonfly](/source/Hine's_emerald_dragonfly) (''Somatochlora hineana''), for example, is an [endangered species](/source/endangered_species) in the United States. Corduliidae are known to occasionally take quantities of their eggs at the tip of their stomach, before then sticking their eggs in mud or water using a sprout-like appendage that extends from their abdomens. ==Selected genera== Genera included in this family are: * ''[Antipodochlora](/source/Antipodochlora)'' {{small|Fraser, 1939}} – dusk dragonfly * ''[Cordulia](/source/Cordulia)'' {{small|Leach, 1815}} – American emeralds * ''[Corduliochlora](/source/Corduliochlora)'' {{small|Marinov & Seidenbusch, 2007}} * ''[Cordulisantosia](/source/Cordulisantosia)'' {{small|Fleck & Costa, 2007}} * ''[Dorocordulia](/source/Dorocordulia)'' {{small|Needham, 1901}} – little emeralds * ''[Epitheca](/source/Epitheca)'' {{small|Burmeister, 1839}} – baskettails * ''[Guadalca](/source/Guadalca)'' {{small|Kimmins, 1957}} * ''[Helocordulia](/source/Helocordulia)'' {{small|Needham, 1901}} – sundragons * ''[Hemicordulia](/source/Hemicordulia)'' {{small|Selys, 1870}} - emeralds * ''[Heteronaias](/source/Heteronaias)'' {{small|Needham & Gyger, 1937}} * ''[Metaphya](/source/Metaphya)'' {{small|Laidlaw, 1912}} – emeralds * ''[Navicordulia](/source/Navicordulia)'' {{small|Machado & Costa, 1995}} * ''[Neurocordulia](/source/Neurocordulia)'' {{small|Selys, 1871}} – shadowdragons * ''[Paracordulia](/source/Paracordulia)'' {{small|Martin, 1906}} * ''[Rialla](/source/Rialla_(genus))'' {{small|Navás, 1915}} * ''[Somatochlora](/source/Somatochlora)'' {{small|Selys, 1871}} – striped emeralds * ''[Williamsonia](/source/Williamsonia_(dragonfly))'' {{small|Davis, 1913}} – boghaunters ==Etymology== The family name ''Corduliidae'' is derived from the type genus ''[Cordulia](/source/Cordulia)'', with the standard zoological suffix ''-idae'' used for animal families. The genus name ''Cordulia'' is derived from the Greek κορδύλη (''kordylē'', "club" or "cudgel"), referring to the shape of the male abdomen. ==References== {{Cite journal|last=Selys-Longchamps|first=E.|year=1850 |title=Revue des odonates ou libellules d'Europe|url=https://www.biodiversitylibrary.org/page/16236415 |journal=Mémoires de la Société Royale des Sciences de Liège |language=French|volume=6 |pages=1-408 [66]|via=[Biodiversity Heritage Library](/source/Biodiversity_Heritage_Library)}} {{Cite journal |last=Dijkstra |first=Klaas-Douwe B. |last2=Bechly |first2=Günter |last3=Bybee |first3=Seth M. |last4=Dow |first4=Rory A. |last5=Dumont |first5=Henri J. |last6=Fleck |first6=Günther |last7=Garrison |first7=Rosser W. |last8=Hämäläinen |first8=Matti |last9=Kalkman |first9=Vincent J. |last10=Karube |first10=Haruki |last11=May |first11=Michael L. |last12=Orr |first12=Albert G. |last13=Paulson |first13=Dennis R. |last14=Rehn |first14=Andrew C. |last15=Theischinger |first15=Günther |date=2013 |title=The classification and diversity of dragonflies and damselflies (Odonata).
