Phyllonorycter blancardella, the spotted tentiform leafminer, is a moth of the family Gracillariidae.

It is also known throughout North America including Nova Scotia, Quebec, Ontario, Wisconsin and California.

White streaks sometimes join together to form larger markings (fascia and spots).

Both species, like many other pests, show an increasing resistance to organophosphate and synthetic pyrethroid insecticides.

[4] Two species of very small wasps, the eulophid Sympiesis marylandensis and the braconid Pholetesor ornigis are parasites of both P. blancardella and P.
