This is a frame from a recent recording:
Forest in Central Europe at around 1pm.
Abiotic factors at the time of recording
- Temperature = 23°C
- Humidity = 38%
- Wind = 6 km/h
- Approximate size = ~3 cm including limbs
- Semi-transparent limbs and cephalothorax, opaque abdomen
- The abdomen presents a pattern which reminds me of the coat pattern in giraffe G. camelopardalis tippelskirchii
- its general morphology makes me think it might be part of Pholcidae family but I'm not entirely sure because the height of the abdomen seems a bit too bulbous on the Y axis
- web structure rather irregular
Very short reaction time (dropped a piece of leaf on top of its web), very fast moving spider. I can't provide a better estimation for the speed, but here's is the 3rd frame after the one above (on the previous two frames it just very slightly flexes its limbs):
And one frame later it's already gone.
- Google image search: no results using the first image you see in this post
- Google text search: different sentences like "long-legged transparent forest spider" only returned the usual daddy long legs you can find at home in urban areas.
- Finally I tried https://spiderid.com/spiders/ selecting white and brown but none of the displayed spiders matches anything that resembles the frame above.
Any help will be much appreciated. I guess the pattern on the abdomen is key to identify this species but I haven't had a lot of luck while looking for abdominal spider patterns.
