#Phyllocnistis populiella

[thebashfulbotanist]

Leaf mines from a larva of the aspen leafminer moth, Phyllocnistis populiella, on a quaking aspen, Populus tremuloides, in Denali National Park in Alaska. Aspen leafminer larvae feed on the epidermal tissue of plant leaves; while they don’t eat photosynthetic material, they indirectly disrupt photosynthesis by destroying guard cells around leaf stomata. Guard cells control when stomata are opened or closed, so they can end up stuck in one position and either prevent carbon dioxide uptake or allow excess water loss. Leaves affected by aspen leafminers often die.  Aspen leafminers tend to experience population increase during warm, dry years, so while they’re native to Alaska, researchers are keeping an eye on them and their impact as climate change warms up the region.

“Trails of life,”

“The forests of the North are beautiful in autumn, with the variety of colours of the trees. A little larvae is an autumnal surprise in the northern woods of Alaska and Yukon. The feeding behaviour of aspen leaf miner (Phyllocnistis populiella) larvae, on the leaves of aspen (Populus tremuloides), make interesting patterns, with intricate trails on every leaf. The floor of the yellow forest becomes a new world to enjoy nature.”
