New year, new lens. The Laowa 100mm 2x macro which on the Canon includes auto-aperture. Canon D90 with an agreeable fly who posed for me. Great detail in the eyes, happy with that! #macrophotography#diptera#flies#insects
... competing with wing loss in flies (flightlessness), at 25 events counted to date. Can't find an up to date citation; a neat phylogenetic tree of #Diptera marking all the apomorphic events was shown to me by Darren Williams. There's Wagner & Liebherr 1992 https://www.sciencedirect.com/science/article/abs/pii/016953479290047F listing 22 insect orders with flightless species: almost all of them have species with secondary wing loss.
Darren Williams showed them to me about a week ago; his lab is working out changes in neuroblast progeny comparing Braula sp. with other drosophilids. Fascinating work. And did you know that secondary wing loss evolved independently many times in #Diptera?
Winter ist doof, weil da viele Insekten fehlen 🙄
Aber es sind ja auch nicht alle #Insekten gleich beliebt, auch wenn diese #Regenbremse (#Haematopota pluvialis) fotogen in die Kamera schaute.
Man könnte denken, dass die Schwarze Augenfleck-#Schwebfliege (#Eristalinus sepulchralis) eine leicht bestimmbare Schwebfliegenart ist, aber es kommt z. B. auf deren Augenbehaarung an.
Many thanks to #iNaturalist’s identifier Erikas Lutovinovas, who just ID’ed a few of my #Diptera observations. Turns out some are very rarely observed:
Here's to a happy #FlyDay to those who celebrate. I don't really know who either of these are, but the gold and black one is bristle fly and the one with the huge eyes is a hoverfly that is likely a Bromeliad Fly (Copestylum sp.)
