Photos / SoundsWhatEastern Pondhawk (Erythemis simplicicollis)ObserverjnstuartDescriptionI'd appreciate opinions if this is an Eastern or Western pondhawk as both species and hybrids/intergrades occur in eastern New Mexico. Taken at Clayton Lake State Park, Union Co., New Mexico, USA. |

WhatGenus GomphusObservererlandreflingnielsenDescriptionI'm not sure if this is Gomphus vulgatissimus or G. schneiderii. It is photographed at the same location as the image below of a male. The two species should be hybridizing in parts of Balkan.

Photos / SoundsWhatCommon Whitetail (Plathemis lydia)ObserverjnstuartDescriptionMale Plathemis lydia, one of two seen on the Barr Interior Drain ditch today at Valle de Oro NWR. The amount of pruinosity on the forewings, as well as hindwings, seems atypical, leaning somewhat towards what you see in Plathemis subornata. Interestingly, a single male P. subornata was discovered at this same spot in August 2017. My first thought was: possible hybrid?? |

Photos / SoundsWhatTule Bluet (Enallagma carunculatum)ObserverumpquamattDescriptionThis is another one with appendages that seem to approach civile, at least from the side. The pattern of black on S10 is also very much like civile. Dorsal black on the remaining abdominal segments is extensive like carunculatum. Could this be a hybrid? |

Photos / SoundsWhatRed-eyed Damselfly (Erythromma najas)Observervladimir_onishkoDescriptionPossibly a hybrid x viridulum. Both species lived on this pond in 2015-2018, but in 2020 only such strange E. najas were found. Males have pronounced shoulder stripes (as in subspecies humerale and E. viridulum) and have bright blue markings on the sides of the S8. Structurally (pronotum and appendages), this is undoubtedly E. najas. |

WhatScarlet Percher (Diplacodes haematodes)ObserverthierrygaloisDescriptionLa coloration de la veine costale fait en effet penser à D. haematodes (ce qui est déterminante pour l'espèce), mais on voit bien deux points latéraux qui pourrait laisser penser à D. bipunctata (ce n'est pas la premiere fois que je vois ça.. on pourrait imaginer une hybridation, bien connue chez les diplacodes, mais pas encore connue entre ces deux espèces; soit qu'il faudrait revoir la clé de détermination suite à ces variabilité phénotypiques. Lieu plaine des étangs de La Tamoa. Nouvelle-Calédonie. |

WhatCommon Baskettail (Epitheca cynosura)ObservermangoverdeDescriptionI usually hesitate to to take E. costalis / cynosura to species but this has cerci noticeably shorter than S9+S10. Not sure where the hybrids fall in this characteristic. |

Photos / SoundsWhatHawkers and Typical Darners (Genus Aeshna)ObserverjimjohnsonDescriptionI am provisionally calling this individual an Aeshna umbrosa x constricta/palmata hybrid since the second parent cannot be confirmed from its appearance (although A. palmata is likely since it is certainly present in the region and A. constricta is unrecorded). Read the complete details here: https://www.researchgate.net/publication/379023371_An_apparent_Aeshna_hybrid_and_a_possible_hybrid_complex |

WhatTropical King Skimmers (Genus Orthemis)ObserverophiogomphusDescription"Antillean Skimmer". Interesting is the shade of pink-purple of the thorax. This is a site where Roseate Skimmer flies in equal abundance with "Antillean Skimmer". Does make me wonder about a hybrid here!! |

Photos / SoundsWhatMigrant Hawker (Aeshna mixta)Observervladimir_onishkoDescriptionPossibly a hybrid between A. soneharai and A. mixta. However, apart from the absence of a yellow triangle on s2, there are no other differences from the typical A. mixta. |
