You're going to laugh, but last night I removed the exuvium from my freshly molted G pulchripes. Was about 2.5cm before the molt, so really tiny.
I put the exuvium on my table and I can only assume that some of the urticating hairs got onto my hand and front part of my other arm. It itched like crazy. I am very prone to skin irritation, so I expect the worse when it comes to urticating hairs.
Will try and take out my B albopilosum today. est. 4.5cm and take some pictures. This is one of the very few slings I have handled. My A versicolor was very unintentional, it just climbed out whenever I opened the lid. With the new enclosure, it doesn't want to get out, so I assume it's happier.
