Cazuma Pincertail
Onychogomphus cazuma
The Cazuma dragonfly is an anisoptera odonate of the Gomphidae family.
Appearance
Cazuma Pincertail imagos are yellow and black dragonflies, with blue eyes, measuring approx. 45 mm total length and 54 mm wingspan. The lower appendage of the male and the vulvar scale of the female are the diagnostic characters that allow this species to be differentiated from the rest of the genus. In addition, they are distinguished by presenting the following combination of characters: black vertex with a rounded yellow spot, yellow thoracic collar not interrupted by a black stripe, and connected antehumeral and postdorsal stripes.
Range and habitat
In the Turia basin it is distributed in the municipalities of Santa Cruz de Moya (Cuenca), Titaguas and Sinarcas (Valencia). In the Mundo River basin it has been detected in Hellín (Albacete) and Mula (Murcia). Finally, it has been found in the Malaga municipality of Ardales, in the Guadalhorce river basin. The Cazuma dragonfly is an anisoptera odonate of the Gomphidae family.
GBIF currently lists 67 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Life history
Life history follows the order: complete metamorphosis in moths and beetles, nymphs in grasshoppers and bugs. This page does not invent a host plant that no source named.
In crisis
The small size of the habitats appropriate for larval development increases the risk of local extinctions, and recolonization from nearby populations is limited by the geographical distances between the different areas of presence. Based solely on distribution criteria, it has been classified as endangered at a global and European level on the IUCN Red List.
