I think with tarantulas if you take an adult female she may be 10 or 20 years old and eventually as old females are taken it will depress the population (assuming there's any natural habitat available) but with mantids, they're seasonal so the oldest female you'll find is 3-6 months of age and you'd have to collect most of the population to have a real impact. Difference between cutting off the fingertip and the fingernail.Hello all! I am a tad of a tarantula hobbyist already and I understand that many people are against taking an invertebrate from its home. I was wondering if this correlates to mantids as well? There’s a native species in my state “The Unicorn Mantis” that I really wish to obtain. Not even sure where to look yet but I live in Arizona so that’s a good start. No matter the reply I will probably continue to look for one unless I find out they are a suffering species, just because me and my friend go night hunting a lot. Maybe one day I will go back and try to breed more. In a long, long time lol.
