Japanese lynx spider Oxyopes macilentus.

Pardosa laevitarsis from Naha, Okinawa, Japan. There were plenty of these guys frolicking in a city park.
In Finland, where I live, we have P. lugubris running around every yard and garden. I guess I found the subtropical equivalent of our beloved “lugu”!

Cyclosa mulmeinensis, the spider inspired by camels.🐫
No, just kidding! Orb-web weavers existed much before camels. So it must be the camels who borrowed from C. mulmeinensis the cool idea of sporting two humps in the back.

Quality crab spider from Okinawa, Japan. I found this elegant green eight-legged pickle in a park in Naha. Species is Oxytate hoshizuna. #thomisidae #spidermacro
Pachygnatha listeri female from Central Finland. Literally, “pachygnatha” means thick jaws, and you can see why in the second photo. Named after naturalist Martin Lister (1639–1712), P. listeri likes to live in the low vegetation of damp forest areas. #tetragnathidae #spidersky
Black Double-Headed Dwarf Spider (Diplocephalus picinus) from Finland. These 2mm long minibeasts live among leaf litter and munch springtails for snacks. #linyphiidae #spidersky

Viime vuonna päätin uudistaa yleistajuisia matikkaesityksiäni niin, etteivät ne tuntuisi luennolta tai oppitunnilta.
Meiju Paxin kanssa käsikirjoitimme show’n ”Harrastajan matematiikka”.
Tervetuloa YouTubeen katsomaan aivan uudenlaista tiedeviestintää!

Yellow-legged wolf spider Pardosa fulvipes.
These nimble buggers prefer Eastern Europe: they have never been found west of Germany and Italy. At my summer cottage in Central Finland P. fulvipes are plentiful. #lycosidae #spidermacro
Bathyphantes nigrinus, tiny spider from leaf litter.
“Bathys” means deep in Greek, and “phantes” refers to appearing. In a bit of a mystical way since both “phantom” and “fantasy” arise from that word.
So Bathyphantes spiders emerge from the deep. #linyphiidae #spidermacro
Orange-legged spider Gongylidium rufipes is a sheet-web weaver from family Linyphiidae. It lives in bushes and undergrowth. G. rufipes is very common in Finland where I live. #spidermacro #linyphiidae #spidersky

It’s just a couple of families, perhaps only those.
Uloborus plumipes: spider without venom.
Usually spiders kill their prey by injecting venom with fangs. But some species wrap an insect with super tangled silk into a tight package and cover it with digestive fluid. After a while the soup is ready.
Athens, Greece. #uloboridae
Pretty little jumper from Athens, Greece. Its home base and hunting ground is National Garden right next to the Syntagma square.
Species: Evarcha jucunda.

Spiders of family Pholcidae have specific eye arrangement: clusters of three eyes on the sides, and two eyes in the middle.
Many species, including Carapoia lutea shown here, have really long slender legs. This has earned them the nickname “daddy long legs spiders”.

Free hugs! But beware of spikes.
