Hi Israel. Thanks for your note. I hope your study is going well. For the ants, Paco (I can't remember his last name right now) at the California Academy of Sciences is likely going to check out our ants. He works with Brian Fisher at Cal Acad. We brought back a considerable amount of alcohol specimens so we're still at the sorting stage on those. For pinned ants, we have Bullet Ants and Leaf Cutter Ant workers, soldiers, and alates. Talk with you later. Cheers, Dave

Hi Oscar. Great observation! This is a male based on his bright colors and also the size of his interfemoral pores (these are pores along the leading edge of what would be equivalent to our femur - males have large pores while females have small pores). I'm only speculating here but oftentimes lizards will have varied patterns to break up their body shape to make it harder for predators (and prey) to see them. This is especially true with the vertical striping - like in zebras - that really break up the body pattern. Also, different developmental genes are at work in the midsection of the body, thus for reproductive success, males exhibit bright colors during the reproductive season - thus the middle of the body serves as this "flag". All-in-all, this collared lizard was a great find.
