Yes but they should know when its day or night to get a natural rythm, those words comes from a spider biologist.Seeing as Anastasia is one of the most reputable breeders of tarantulas in the U.S. I'm going to side with her. It doesn't seem to be effecting her ability to get egg sacs at all.
So, no light isn't a must for tarantulas. They are nocturnal after all.
I highly doubt that tarantulas go by daylight to know their seasonsI'd think they need light too, to synchronize their circadian rhythm...but I don't know if a 12 hour cycle is particularly useful or if they can make do with an irregular or a northern seasonal cycle of light (long days in the summer, short days in the winter).
There are several species that like to bask. Most notably those of the genus psalmopoeus. All of my psalmos love the sun and during the summer I let them out so they can enjoy it.I had two adult female Brachypelma smithi's that would bask in sunlight on occasion. During the evening when the sun was setting there was a section of their container that the sun would shine on. I've caught them sitting in that section many times and even seen them turn around to allow the sun to shine on their other side. This was during the summer when temps in my home were in the mid 70's.
Aren't most of them tropical and used to 12 hours light/dark? Do they need sunlight and UVB? Maybe not, but I think they'd do best with light to signify day/night.I highly doubt that tarantulas go by daylight to know their seasons
just talking from experience of keeping
none of mine see daylight period.
my spider room is in basement no windows, I have one small night plug in light by the door so if I need to sneak in I dont break my neck
but sure if some one can point scientifically significant information that sunlight is necessity or real benefit for tarantulas I'd like to see it
other wise, next step is daylight saving time in check, heck I go broke buy all mine watches ;P
Lol, yeah I can imagine that bill.I'd like to see it
