Day/Night [Haiku]

This is an intriguing haiku, ether; very Matsuo Basho-like in composition.
As I'm sure you already know, every haiku has two parts to it. It's divided in the middle by what's called a "cutting word." It's a structure that is designed to engage the reader, and it permits multiple interpretations to this potent poetic form.
Your kigo, or seasonal reference, is rather vague. However, it implies spring or summer as spiders cannot survive the cold, brutal temperatures in colder climates.
You final line; the satori, is a illuminating observation of the poem in its entirety.

You've opted for the more westernized 5-7-5 syllabic count traditionally utilized by western haiku poets. 17 syllables, or LESS, is also perfectly acceptable, as the Japanese do not count syllables when creating haiku. Instead, they go by sounds, or how each word sounds in Japanese when read.

Nicely done...

Excellent haiku, ether.
Lines one and two have a distinctly grammatical connection as required.
Your "kigo", or seasonal reference, could pertain to spring, summer or even fall since spiders are prevalent during those seasons outdoors.
Using sunny Sol as a giant spider-like eater of stars is a great metaphor.
Your satori is a brilliant (no pun intended) observation of the events as they unfold in the "here and now."
You've opted for a more traditional westernized 5/7/5 format, although the Japanese haiku poets utilize sounds, not syllables, and any poem pertaining to nature, or man's relationship TO nature, which uses 17 syllables or LESS is acceptable.

Great imaginary.
I can say its a perfect haiku, and its beautiful.
5 out of 5 stars for you.

Ether, this is enthralling and wonderful.

The contrast in imagery is beautiful.you portray so much in so little.

Hello Ether

Lovely imagery conjured in these three lines. I love the short forms and write a fair few senryu but have always struggled with haiku.

Well done and all the best
