}}Blastodacna bicristatella is a moth in the family Elachistidae. It was described by Vactor Tousey Chambers in 1875.[1] It is found in North America, where it has been recorded from Illinois, Indiana, Kentucky, Ohio and Quebec.[2] The wingspan is 12 mm. The forewings are pale ochreous, dusted and suffused with brown. There is an oblong tuft of dark brown raised scales on the fold and a short brown streak between it and the dorsal margin. There is another tuft of brown scales at the end of the cell and the apical part of the wing is dark brown.[3] Adults have been recorded on wing in May and June. The larvae feed on Crataegus species. They feed inside the fruit of their host plant. The species overwinters in the pupal stage.[4] References1. ^{{cite web |url=http://www.nhm.ac.uk/our-science/data/lepindex/search/ |title=Scientific name search |website=The Global Lepidoptera Names Index |publisher=Natural History Museum}} {{Taxonbar|from=Q13440053}}{{Elachistidae-stub}}2. ^Moth Photographers Group at Mississippi State University 3. ^[https://archive.org/stream/canadianentomolo07ento#page/210/mode/1up The Canadian Entomologist 7 (11): 210] 4. ^Microleps.org 2 : Moths described in 1875|Blastodacna |
