Plattbauch Weibchen
Libellen haben lange, von einem dichten Adernetz durchzogenen Flügel.
Die Flügel sind, insbesondere in der vorderen Hälfte, von einer Reihe sehr stabiler Längsadern durchzogen.
Diese Flügeladern bilden das „Flügelgerippe", zwischen dem die Flügel aufgespannt werden.
Ein Netz feiner Queradern verbindet die Längsadern. Sie erhöhen als Verstrebung die Gesamtstabilität der Flügel.
Die Flügel der Libellen sind keine tote Gebilde. Sie weisen ein Röhrennetz auf, durch das das Blut zirkulieren kann. Die Färbungen der Flügelflächen können die Libellen zur Kommunikation einsetzen.

Dragonflies have long wings crisscrossed by a dense network of veins.
The wings, especially in the leading half, are traversed by a series of very strong longitudinal veins.
These veins form the "wing skeleton" between which the wings are stretched.
A network of fine cross veins connects the longitudinal veins. These act as bracing, increasing the overall stability of the wings.
Dragonfly wings are not inert structures. They contain a network of tubes through which blood can circulate. Dragonflies can use the coloration of their wings for communication.

It turns out I had a dodgy camera on my drone! I was a tad bit disappointed with the image quality when I first got it but put this down to me being used to the sharpness of the 5D and L lenses. I began to wonder I had a duff when when other people were experiencing concerns on DJI's forum too. I sent some RAW files to DJI and they confirmed the camera was faulty, anyway, I got a replacement drone and image sharpness is loads better.
Now I have to re shoot the lock shots I took over the past few weeks, this being the first. The colours are also loads better from the Phantom so I've decided not to process in mono!
37425 ‘Sir William McAlpine/Concrete Bob' is captured at Breydon, near Great Yarmouth, on Thursday 24th April 2025. The Regional Railways livery 'Tractor' and BR Large Logo 37402 'Oor Wullie' combined again this month for the East Anglia Network Rail PLPR test Train. Thankfully the cloud bank that had covered Norfolk for the majority of the day had pushed west enough to coincide with 1Q98's visit to the seaside town. (Photo taken with pole)
