Presented my poster at the IPC today. First time ever and also my first conference ever! Very scary!! >.< But I’m really happy with how it went, overall! :D The IPC is great! So much fun! So much interesting stuff! (Free cake as well!) Aaaaahdhfjdjdjdjdfjdjs :D
Drosophila eggs look surprisingly cool under the microscope! Kinda makes me want to look at eggs of other insects too! #microscopy #macrophotography #zoology #drosophila
I’ve been really quiet on here lately since I’ve been busy with designing a poster for IPC15. Aaaaah I’m so excited!! (It will be the first conference for me) Anyway, I fear I’ve left my page unattended for so long that mould has started to appear. Oh no! :0 #microscopy #fungi #mould #photography
I've had an idea in my sketchbook for awhile to draw cryptic moths (eg waved umber, green carpet) with part of the background faded or cut out. So you could appreciate how effective their camouflage is, & also how beautiful they are in their own right. I never got time to try it tho… Until now! 😁
So the bad news is that my plants have thrips. 😓 The good news is that I got a great photo! #thrips #microscopy #entomology
I was very surprised to find this beetle larva in my marine/brackish water sample today. I thought aquatic beetle larvae occurred exclusively in fresh water! If you have any idea as to what species/genus/family this belongs to, please let me know. I’m very curious! :D #microscopy #beetle #larva
I went to the sea last week and took some water for microscopy. Found a flatworm and just look at those cells! So pretty :D #microscopy #wormwednesday #flatworm
Found three different species of pseudoscorpions yesterday and they‘re all from different species as well! :D #arthropod #mesofauna #pseudoscorpion #arachnid
I can finally share the Giant Clam illustration I created for @20kleagueszine.bsky.social !! 🐠🐡🦑 #invert This was my favorite illustration of 2025 :) My papercraft has evolved considerably over the last few years
Flabellospora acuminata - in a foam sample from northern hessia from last december. #AquaticHyphomycetes
I don’t remember whether I posted this one, but for this #WormWednesday here‘s Alentia gelatinosa! 🪱 #MarineLife #Polychaete
iNatting for the City Nature Challenge with spectacular scenery! #landscape #nature #iNat #citynaturechallenge
If life hands you a deadline, draw polychaete stickers! (Am supposed to be working on velvet worm nephridia, but oh well…) #polychaete #worm #art #marinelife
Onychophorans are weird. They have 3 different kinds of nephridia. Small ones in the first 3 pairs of legs. Huge ones in 4 and 5. And „typical“ ones in all the remaining ones. Also in 4 or 5, instead of having the opening (nephridiopore) at the base of the legs, they open right at the feet. Wth??
Die letzten Wochen war hier alles gefroren. Einzig ein Entwässerungsgraben war eisfrei, aber in dem gibt es nur Ruderfußkrebse. Darum habe ich ausführlich Copepoden fotografiert. Von dorsal und ventral
Harpacticoida Copepoden sind nicht leicht zu fotografieren. Ich habe nur sehr wenige Fotos von denen. Heute habe ich ein Weibchen ventral mit angehängter Spermatophore ablichten können.
Breaking news! I have successfully adapted the camera to my microscope! Yaaay! Still need a bit more distance for parfocality with the eye pieces, so I‘m ordering a helicoid extension tube.
Went to a marine exhibition at the Bundeskunsthalle today. Great exhibition all the way through. But I was particularly stunned by the crocheted coral reef. I think this is one of the most beautiful and impressive works of art I‘ve seen. It‘s a collaboration by a few hundred (>1000?) artists.
Hello cutie squish squash Spionidae larva! A gorgeous little polychaete (bristle worm) larva from last week’s sample. #marineplankton 🦑
oh interesting! A polychaete Phyllodoce mucosa surrounding this green ball! is that where the species epithet comes from ? A mucus ball? eggs? interesting! #wormwednesday www.inaturalist.org/observations...

Just a photo from yesterday‘s walk that‘s horribly overexposed, but that I like a lot. Spring is here! :D #cherryblossom #spring
Joining in with the reference vs. art thing 🌿
Three copepods under UV from my sample last week. A female Pseudodiaptomus marinus, a female Pseudocalanus sp., and a Harpacticoida (I don’t know genus). #marineplankton 🦑
