  • $\begingroup$ If you don't find an answere here find an entomology forum or "what's this bug" because the ID is very specialized entomology. $\endgroup$ Dec 19, 2020 at 7:54

This appears to be the wing of a crane fly (Tipulidae). Using this figure you can begin narrowing down the possibilities for wing venation. Searching diptera wing venation, I think, brings up this excellent diagram (see bottom left for Tipulidae) which quite closely matches your photo if rotated in a graphics program (GIMP):

You could likely drill this down further by searching Tipulidae venation or the like on Google Scholar, which pulls up many papers with detailed information on various regions and taxa of crane flies.

  • $\begingroup$ You might further cite evidence that crane flies have wings this size. For example, quickly Wikipedia suggests they can range from 1-6.5(11) cm, which safely includes the size of the OP's specimen. You might also note that crane flies are present in DC. $\endgroup$ Jan 18, 2021 at 20:34
