Highly relevant is the Portia genus of spiders ([0], [1]) and apparently other related jumping spiders ([2]).

One of my favorite excerpts from [1]:

> Harland says Portia’s eyesight is the place to start. Jumping spiders already have excellent vision and Portia’s is ten times as good, making it sharper than most mammals. However being so small, there is a trade-off in that Portia can only focus its eyes on a tiny spot. It has to build up a picture of the world by scanning almost pixel by pixel across the visual scene. Whatever Portia ends up seeing, the information is accumulated slowly, as if peering through a keyhole, over many minutes. So there might be something a little like visual experience, but nothing like a full and “all at once” experience of a visual field.

Portia spiders are also referenced in Peter Watts' Echopraxia. (Some spoilers could be inferred from thinking about this too hard while reading the novel.)

Not.. if you don't say that...

Re:How insects like bumblebees do so much with tiny brains by pavel_lishin on Tuesday January 24, 2017 @11:56AM (#13473067)
Yeah, I guess it's a bit like saying "don't think about a pink elephant", but not saying that doesn't guarantee that they won't think of a pink elephant.

And I'd wager that people who would read about the Portia, and would read Blindsight and Echopraxia are the type to think long and hard about such topics anyway.

Well, iirc they do actually reference these spiders right there in the novel, so it's not THAT much of a spoiler.
Re:How insects like bumblebees do so much with tiny brains by smallnamespace on Tuesday January 24, 2017 @02:43PM (#13474766)
Adrian Tchaikovsky's Children of Time is another novel where Portia spiders are featured prominently (great book btw).
Re:How insects like bumblebees do so much with tiny brains by joshmarlow on Tuesday January 24, 2017 @10:19AM (#13471980)
Yep! Watts' novels are how I first heard about Portia. I can't wait for the third in the trilogy.

In general, I love a good novel with a bibliography.

For people who don't believe that spiders can be cute:

https://adlayasanimals.files.wordpress.com/2015/01/u2byv.jpg

Also, I got interested and tried to find some documentation on Portia Labiata after reading Watts' book, and there's very, very little, but what he says appears to be true. They do have telescopic eyes with vibrating retinas. They do spend ages painstakingly scanning a scene before moving. They are absurdly intelligent for insects. I don't know if Watts' suggestion that they timeshare pattern-matching areas of their brains is true, but it seems plausible.

Here's a good article: http://www.dichotomistic.com/mind_readings_spider%20minds.ht...

If you're afraid of spiders, I would suggest not clicking on that link. I was hoping for cute, but that is just a very large closeup of a spider, and it definitely just hit the fear instinct.

That one is ugly. The jumping spiders have a neater look due to their colors. The really colorful ones with big eyes might not hit fear instinct so hard. Try this one I cherry-picked:

Props for sourcing your images! That is often overlooked by just about everyone (especially when trying to meme for a buck) and breaks at least the spirit of the web.

The ugly scary spider is much cuter with the green channel inverted.

Re:How insects like bumblebees do so much with tiny brains by panxie on Tuesday January 24, 2017 @11:56AM (#13473064)
In English is it correct to say spiders are insects? In my native language (portuguese) it would be not accurate, as they are arachnida class, along with scorpions,mites and ticks.
Re:How insects like bumblebees do so much with tiny brains by sqeaky on Tuesday January 24, 2017 @01:08PM (#13473852)
A good word for something that encompasses all things creepy, crawly and tiny without involving scientific classification is "bug". Most english would agree that most spiders, ants, bees, centipedes and other like it are all bugs.

This breaks down in Australia where the spiders are as big as your head or in Puerto Rico where the foot long centipedes eat bats. Those aren't bugs, those are nightmare fuel.

Re:How insects like bumblebees do so much with tiny brains by david-given on Tuesday January 24, 2017 @02:41PM (#13474755)
'Bug' in that context is mostly American dialect. I'm British, and 'bug' in that context is infantile; by adults, it's either a verb or a small device planted by MI5.

But the OP is right, of course. Spiders are not insects. Although I suspect that most people I'd talk to in the UK would call them such. I'll have to hand in my Pedant's Society card (which is actually made out of plastic)...

Re:How insects like bumblebees do so much with tiny brains by dghughes on Tuesday January 24, 2017 @03:34PM (#13475203)
Then again the little grey oval Pill bug is a crustacean not an insect and not an arachnid.
Re:How insects like bumblebees do so much with tiny brains by pacaro on Tuesday January 24, 2017 @03:58PM (#13475376)
And also another source of British vs. American dialect difference/confusion. In my experience, they're known in the U.K. as "woodlice", but in the US it's entirely reasonable for grown adults to refer to them as "roly-polys"

The American use of "critter" also bemuses

Re:How insects like bumblebees do so much with tiny brains by hnal943 on Tuesday January 24, 2017 @04:54PM (#13475979)
"critter" is a corruption of "creature" and distinctly southern USA (to my Midwestern ears).
Re:How insects like bumblebees do so much with tiny brains by nickff on Tuesday January 24, 2017 @11:59AM (#13473098)
Spiders are not insects; from Wikipedia:

"terrestrial arthropods, such as centipedes, millipedes, scorpions, and spiders, are sometimes confused with insects"[1]

Re:How insects like bumblebees do so much with tiny brains by chc on Tuesday January 24, 2017 @12:46PM (#13473603)
It's not correct, but it's a pretty common mistake to refer to bugs in general as "insects."
Re:How insects like bumblebees do so much with tiny brains by pavel_lishin on Tuesday January 24, 2017 @12:58PM (#13473739)
And even saying "bugs in general" is technically inaccurate!

Not among biologists :)

In real life many people call spiders insects, either from ignorance or from not caring about the distinction.

Re:How insects like bumblebees do so much with tiny brains by dspillett on Wednesday January 25, 2017 @05:43AM (#13480313)
No, they are not referred to as insects in (correct) English either, they are arachnids - though sometimes people do not make the distinction.

To refer to both insects and spiders & similar in one term you could use the (rather less formal) terms "bugs" or "creepy crawlies". I can 't think of anything more formal off the top of my head.

Last I saw, was what looked like a video game based on Blindsight.

Quickly skimming those but I think I've read most of those I do recall reading the Portia spider's eyes don't move but instead it rotates its brain.

It can mimic the footsteps of other spiders by plucking the web of the spider it's going to kill.

Doesn't the name comes from Portia in the Merchant of Venice a devious character?

Jumping spiders are cool we have the stripy ones in my region. Spider give me the creeps but not jumping spiders I think it's due to the shorter legs and small size.

Re:How insects like bumblebees do so much with tiny brains by stil on Tuesday January 24, 2017 @09:00PM (#13477775)
That's so different from our concept of vision. It would be like watching a web cam that surveils a park, but only refreshes small bits of the screen at a time. You might see a headless woman strolling along, etc
