Male 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??

This 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?

Possibly 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.

La 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.
