Leaf mine in Sweet Indian Plantain, 1914 herbarium specimen - Phyllocnistis insignis

Leaf mine in Sweet Indian Plantain, 1914 herbarium specimen - Phyllocnistis insignis
Davenport, Scott County, Iowa, USA
September 16, 1914
Size: ~1 mm wide
I encountered this 1914 specimen of Sweet Indian Plantain (Cacalia [Hasteola] suaveolens) in the herbarium of the Putnam Museum and spotted twisting mines in a leaf which I recognized as those of Phyllocnistis insignis based on previous identification of a different herbarium specimen:


I thought this was a neat illustration of the value of biological collections, in this case documenting the presence of the moth nearly 100 years ago.
