Thank you, excellent point. It reminds me of the laws against international trade in tarantulas of the genus Brachypelma, intended to protect those species and conserve them. However, those laws do NOT address the biggest threat to the T's, which is destruction of and loss of habitat. I've collected and sold K. hibernalis from the colonies on our property, and their environment was left very much as-is, since it's also MY environment. If someone wants a mature female, I either have to catch one, or that person is going to have to wait many years for a 'sling to reach maturity, and honestly, for a female, I have no idea how many years that would be. I just had a male mature out that was six years old, and he probably matured quicker than a wild one, and I've got females that old that still aren't much bigger than my thumbnail, compared to an adult that will cover the palm of my hand. If someone, for whatever reasons, wanted a Neoscona or Argiope aurantica, I've got plenty of those, and the environment would be able to sustain that collection with no impact at all. The demand for true spiders simply isn't that great that collecting of most species for the limited market is going to make a dent, and unless it's a burrowing species and you have to go digging it up, there is no damage to the environment.CA has almost no state level laws about catching or selling terrestrial inverts, so you really just need to be concerned with more local laws. state level laws are almost all species specific and have to do with endangered animals (and are mostly beetle and butterfly species, iirc). all the state level animal laws don't apply because fish & wildlife kindly defined animal to exclude land living bugs. also, catch and sell whatever you can... unless you are using gas flooding or something like that you aren't going to ding any local species. if you have access to critters people are interested in and collect at all responsibly, more power to you. that being said, if you are flipping or digging or using other invasive catch techniques it is pretty important to restore habitat as close to cherry as you can.
think of it like this... the most devoted wild catcher can do hundreds or thousands of specimens of most spiders over their life time. one square mile of land, in range, getting developed will result in many times that number eventually dying. so really, responsible wild catching is more in tune with conservation than never doing anything![]()
