AphidTrek is about aphids (and a little about psyllids), travel, and outdoor adventure. Join us to learn about aphids and to see some cool places.

Most of the information here is about our weekends and vacations — about our hobbies. But sometimes aphid field biology is practical and important. See our ‘Research & Services’ page for ways that we might be able to assist you in agricultural pest management, entomology research, and more.
I (Andy Jensen) have been avidly collecting aphids most growing seasons since 1988. My aphid collection is almost 11,000 slides, with probably at least 28,000 specimens (being entirely funded by my personal bank account, I conserve money and time by mounting 3 or 4 specimens on each slide) of about 610 identified species.

I love the old-fashioned natural history of studying animals and plants in their natural habitats by simply going out in the field and looking at what they do, what they eat, and where they live. Because my Ph.D. was in aphid research, it is aphids that I happen to collect along the way. Working on a group of plant-feeding insects means I know a lot of botany too, and much of my field work is simple ‘botanizing.’ I enjoy learning, and the area of learning I’ve chosen to devote myself to is the natural world of plants and insects.
