Cool! It’s a young crab spider, possibly genus Mecaphesa. They can change color to match their surroundings, but I think it takes a juvenile longer because they change colors with molts. The adults change color by shifting the location of chemicals in the body.

Wow! Thanks for taking the time to let me know, that’s so interesting! Do you think the picture I have up that was identified as a feather legged orb weaver may be one of these? Orb weaver didn’t seem right to me in the first place but I didn’t know enough to question it.

Itsy Bitsy is our Site Moderator. She has at least ten years more experience doing this than I do. She is very thorough and knowledgeable about her identifications. It is okay to question our identifications, we don’t take it personally and sometimes we’re wrong. We don’t mind explaining how we reached our conclusions.

That’s a good question. We would love for that to happen, kinda an universal dream, but it is technically unlikely. I’m a stamp collector and I have achieved the universal collector dream of finding an example of a never documented stamp that was expertised and was given its own catalog number. That is similar, but an easier process than proving that you found an undocumented species. I think a new species has to be studied with physical specimens, possibly of both genders and varying developmental ages. Genetic testing may be done now. All named species have to be ruled out.… Read more »
