Its not easy to photograph these guys. I'm still trying. Its June and every June millions of these guys pass through Ambergris caye. It starts about half way through the month and goes on for weeks. Day and night they flow by.
A few years back I thought I was seeing things when it looked like it was snowing! LOL Amoung the thousands of yellow ones there would be a black one. Where do they hatch (come from) and where are they going?
