This guy was about 6mm long. In Colombia.
Tiny Jumping Spider
As with your orb weavers, I regret that I cannot provide a more specific i.d. at this time. If this spider were in North America, I would say that it looks like a Phidippus sp,. but that genus does not appear to occur in Colombia.
Thank you appreciate your efforts. I know I should seek local information sources but I havenīt found any for insects.
