At night, I would leave a white sheet and UV light in my backyard, rising at 5 am to inspect the harvest. By the time I was an adult, I could identify about 700 butterfly and moth species by sight In 1972, I moved to Australia and continued collecting. I started to struggle. The species on the other side of the world were so different from those at home. Then, through the 1970s, I led expeditions to Papua New Guinea to collect moths in the mountains. One night, we turned on our lights and ended up collecting more than 2,000 different species from a single spot.
The process of identifying each of them felt overwhelming. I gave up.
Two decades later, I was in a supermarket and an idea started to develop: what if a segment of DNA could be used to differentiate between species? Just 13 lines on barcodes were being used to identify everything around me.
