This Monday goes to the forest floor dweller Macrargus rufus. I found this 4mm long beast by sifting leaf litter. This species is abundant all over Finland. The ID process was arduous until I noticed the crooked “glass spear” in the pedipalp. #linyphiidae #spider

Salticus cingulatus jumping spider. Actually, the Latin verb “saltare” means both “to jump” and “to dance”. So is this a dancing spider, after all? 💃 #salticidae #spidermacro
