In its own words:
All things Arachnid: Articles, Photos, Videos, Questions and ID Requests are welcome here.
Community guide
r/spiders (#905, about 1.2 million) covers arachnids—IDs, photos, articles—with strict anti-misinfo and anti-kill-it-with-fire norms, not Spider-Man fandom.
What belongs
Arachnid media and ID requests (about 107 posts/day; heavy image/gallery). Rules: amateurs must not advise on medically significant spiders; include location on IDs; no “is this a spider bite?”; no anecdotal bite stories; no anti-spider “nopes”; memes only Monday; stay civil.
Versus whatsthisbug
whatsthisbug is all arthropods. spiders is arachnid-focused with medical-significance comment limits.
Practical pointers
Always add geography on ID posts; leave medical significance to qualified commenters.
