Life in a leaf: The wonderful world of leafminers

Charley Eiseman

Freelance naturalist and author

Leafminers are insect larvae that spend at least part of their lives feeding between the epidermal layers of leaves. Over 2000 species of moths, flies, beetles, and sawflies are found in North America. Leafminers are usually host-specific, and the mines vary considerably depending on what insect produces it. As a result, it is often possible to identify the responsible insect using only the hostplant and mine characteristics. After eight years of research, traveling throughout the continent, and collecting and rearing thousands of leafminers, Charley has completed a guide to the North American species that includes keys to the mines found on each plant genus. He will introduce the major groups of leafminers, as well as share some new discoveries.

The talk is free and open to the public. The meeting is readily accessible via public transportation. Parking is available in the Oxford Street Garage with advance arrangement, as described here, or (usually but not always) at spaces on nearby streets. Everyone is also welcome to join us for dinner before the talk (beginning at 5:45 PM) at the Cambridge Common, 1667 Mass Ave., Cambridge.

CEC meetings are held the second Tuesday of the month from October through May. The evening schedule typically includes an informal dinner (5:45 to 7:15 PM) followed by our formal meeting (7:30 – 9:00 PM). The latter begins with club business and is followed by a 60-minute entomology related presentation. Membership is open to amateur and professional entomologists.

Can a leafhopper rescue tea from climate change?

Eric Scott

Ph.D. Candidate, Tufts University

When insect herbivores feed on agricultural crops, they are labeled as destructive “pests”. In addition to decreasing crop yields, feeding by insects causes plants to defend themselves by producing secondary metabolites, many of which are important for the flavor and aroma of our foods. Tea farmers in Taiwan began taking advantage of this phenomenon in the 1930s to produce a high-quality tea called “Eastern Beauty Oolong” which can only be made from tea plants infested with the tea green leafhopper, Empoasca onukii. However, as the climate changes, the abundance of agricultural pests is expected to increase, which could threaten this innovative style of tea through changes in tea plant chemistry as leafhopper damage increases.
