Wildlife Spotting

Thank you Mariajo for the description and thank you yiya62 for the translation! "These flies look like butterflies but their wings are hairy and not with scales. They are not active during the day, but they start to move at dusk; they are close to water as their larvae live there. It is hard to identify the different species of fly but if you observe the "quiver" it is easier, since each type of fly puts it together in a different way. To put together the quiver, the larvae use twigs, forming structures, little pebbles, snail shell pieces, leaves and many other things."
