Our summer fundraiser has arrived, and we need your help!
We depend on donations to keep Butterflies and Moths of North America online and free. If everyone who uses this resource makes a donation, we could cover our ongoing costs, develop new features, upgrade the system, and maybe even remove those pesky ads. Please make a one-time or recurring donation to show your support for this valuable source of information. Thank you!
Identification: Three very similar-looking Phyllonorycter species that occur east of the Rockies develop as larvae in underside tentiform mines in the leaves of trees in the rose family (Rosaceae). They are P. crataegella (Apple Blotch Leafminer, on hawthorn and apple), P. propinquinella (Cherry Blotch Miner Moth, apparently restricted to wild cherry), and the introduced P. blancardella (Spotted Tentiform Leafminer, on apple.) Differentiating the adults requires dissection and examination of genitalia.
Taxonomy Notes: None.
National Moth Week was July 23-31, 2022!
Moths are amazing creatures. Take photographs and share your moth sightings with us to document the moths where you live. Learn more.
