Today the tarantula I got last Saturday started with creating a web. At first I thought it was going into hiding and prepare for a molt. On the other hand, as some others had stated too, the tarantula looked like it had recently molted.
Anyway, it turned out to be a so called sperm web, so it's an adult male Brachypelma vagans (Mexican Red-Rump).
In the evening Esme and I went to the city. I bought 2 books at the second hand book store.
