what insect prevents chlorophyll from breaking down in poplar leaves - Ectoedemia argyropeza
Hartland, Windsor County, Vermont, USA

I believe an insect causes small sections of trembling and big-tooth aspen leaves to retain their chlorophyll and continue photosynthesizing in order for the insect to obtain food. I do not know the identity of the insect and would love to.

You might want to...
... ask a botanist or an arborist about this. Show them that picture, or one like it. Plant nurseries, cooperative extensions, park rangers, and high school or college biology departments are among the possible places to find people who might know.

There are a lot of things that can make leaves fall off before they've fully changed color.

The most visible damage in your picture is the brown spots on the yellow/red areas, a dark linear area along the bottom of the right main rib, and a brown patch near the bottom of the green area. Also, a darkened area on the petiole (leaf stalk). It's not clear to me whether any of these things are due to insects.

If this is occurring only with the aspen species you mention, and not other kinds of trees in the vicinity, that's worth mentioning.

poplar leaf
Thanks so much, Kurt. I have discovered it is probably Ectoedemia argyropeza.
