Neriene emphana, the striped-butt sheet-web weaver. #spidermacro #linyphiidae

Diplostyla concolor, a lovely dwarf spider from Central Finland. I caught this mini-beast by sifting leaf litter.

I find the name “concolor” funny since it literally means “all one color”. However, the front part (prosoma) and rear part (opisthosoma) have different colors…

#spidersky #linyphiidae

Japanese orchard spider Leucauge blanda.

These guys weave a horizontal web and hunt beneath it, hanging upside down. That’s why they are easily confused with sheet-web weavers of family Linyphiidae, although they actually represent family #tetragnathidae

#spidersky

Orb-weaver spider Neoscona subpullata from Naha, Okinawa. #spidersky #mondayspider #araneidae

Diaea subdola crab spider from Japan.

I know its cousin Diaea dorsata from Finland; they look much alike. #thomisidae #spidermacro

Hasarius adansoni jumping spider from Okinawa, Japan. #salticidae #jumpingspider #spidersky

Japanese lynx spider Oxyopes macilentus.
#oxyopidae #spidermacro

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”!

#lycosidae #spidermacro #spidersky

Thiania sp. jumping spider from Okinawa, Japan.

#salticidae #spidermacro

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.

#spidermacro #araneidae #cyclosa

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

This Monday’s arachnid is Piratula hygrophila, a wolf spider that “loves water” by name. Indeed, this species thrives in wet and damp ground level habitats. #lycosidae #spidermacro

Harrastajan matematiikka YouTube video by Samun tiedekanava

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

Meet Lepthyphantes leprosus, a dwarf spider with a rare preference of living indoors. My wife found this 3mm long minibeast from our kitchen wall in Central Helsinki. #linyphiidae #spidermacro #spidersky

Young male Theridion sp. found next to Acropolis in Athens, Greece. #theridiidae #spidermacro #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.

#salticidae #spidermacro

Monday spider time! Frontinellina frutetorum from Athens, Greece.

It’s Monday, so it’s spider!

Heliophanus kochii, a stunning jumper I found on a public beach in Piraeus, Greece.
