Plecoptera indet.

[ES] Esta exuvia de una ninfa de plecóptero era tan grande que llamó mi atención desde lejos. No es una foto bonita, pero sí es interesante.
Los plecópteros pasan la mayor parte de su vida como ninfas bajo el agua; los adultos tienen la única función de reproducirse, por lo que viven pocos días o semanas. Están asociados a aguas limpias y oxigenadas, por lo que su presencia es indicadora de la calidad de las aguas.
Si queréis más información, no consultéis la wikipedia, cuya página dedicada a los plecópteros es un despropósito, mejor leed esta publicación de la Sociedad Entomológica Aragonesa: http://sea-entomologia.org/IDE@/revista_43.pdf

[EN] This exuvia was so big it caught my attention from the distance. This is not a nice photo, but it is itneresting.
Stoneflies spend most of their lives as nymphs under the water; adults live only a few days or weeks just to reproduce. They appear in clear, oxygenated waters, so they are good indicators of water quality.
This page from the Entomologycal Society of Aragón has a lot of good information about this order (in Spanish): http://sea-entomologia.org/IDE@/revista_43.pdf

Human-driven #evolution of color in a stonefly mimic https://www.science.org/doi/10.1126/science.ado5331

"As its predators and the poisonous species it mimics have vanished from many regions, there is no longer much point in displaying warning colouration... Zelandoperla populations from deforested habitats have quickly lost their spectacular mimic colouration."

Stoneflies change colour in response to deforestation, suggesting humans can alter evolution – new research

A new study shows that rapid loss of forests has prompted a colour change in stoneflies, caused by a genetic mutation. This means human change to the environment can drive evolution.

Excellent day sampling the #Stellako #River (British Columbia) for #aquatic #insects yesterday. Tons of #stoneflies, #mayflies, and #caddisflies.

#entomology #insect peeps,
Anyone know of any research on what happens to winter #stoneflies when there is no winter?
