A pretty meh day but still managed to see several spiders:
- a mesh-web weaver couple
- a crab spider, something in Coriarachnini
- _Attulus fasciger_ with that teeny tiny posterior median eye clearly visible
- a cobweb spider, maybe _Enoplognatha_?

#SpiderSunday: several of the spiders I met on that one warm day last week! A running crab spider (_Philodromus_), a bold jumping spider (_Phidippus audax_), some kind of crab spider in tribe Coriarachnini (_Bassaniana_?), and a good old zebra jumping spider (_Salticus scenicus_) with what looks like most of a mesh-web weaver (family Dictynidae).

Got some footage of a mesh-web weaver (family Dictynidae) back-combing her silk to make it fuzzy!
It doesn't just tangle up insects; several years ago research showed the silk melds with the waxy coating of some insect cuticles on the molecular level. https://royalsocietypublishing.org/doi/10.1098/rspb.2017.0363

#Arachtober 12: Mesh-web weavers (family Dictynidae) are so small they can easily make a web in a single leaf. This one has caught a long-legged fly (family Dolichopodidae).

#Arachtober 10: from back in June, a mesh-web weaver (family Dictynidae) back-combing a line of silk to turn it into a fuzz of nanofibres. Spiders like this have a special sieve-like silk-making organ called a cribellum. This in fact is the ancestral state of most spiders.
Cribellate silk doesn't use glue; rather, it melds with the waxy compounds on some insect exoskeletons. It doesn't stick very well to other surfaces. Later in spider evolution, spiders developed other types of silk that could catch different insects and support more ambitious aerial webs. However, for a minority of spiders, cribellate silk still works just fine.

Conifer cones are like high-rises for tiny spiders. Every one holds countless silk apartments, some with spiders still inside, like the dictynid in the last picture.
From my Ontario Place visit a couple weeks ago: a tiny spiderling ballooning from a fence post, on an unseasonably warm afternoon. #Araneidae? #Dictynidae?
