I am interesting to learn some species identification keys in order Diptera and Lepidoptera. if you have any references or books which I could use for this purposes please let me know.
3. If you check the authors of these papers, you may find their e-mail address and they will provide any helpo you need for Lepidoptera identification. :)
Also, please check the reference list of the end of this paper: the necessary books and papers are listed which you need to identify the Lepidoptera of your home country.
To have copies of these papers, you need to ask the help or of your institute, university or find a scientific found.
Helpful interactive source for fly morphology you can find here:

For some dipterous families are revisions for Sri Lanka available: just google them...
Another important resources is the catalog for the Oriental region:
Delfinado, M.D. & D.E. Hardy, eds. 1973. A catalog of the Diptera of the Oriental Region. Volume I. Suborder Nematocera. University Press of Hawaii, Honolulu. [vii] + 618 p.
Delfinado, M.D. & D.E. Hardy, eds. 1975. A catalog of the Diptera of the Oriental Region. Volume II. Suborder Brachycera through division Aschiza, suborder Cyclorrhapha. University Press of Hawaii, Honolulu. [ix] + 459 p.
Delfinado, M.D. & D.E. Hardy, eds. 1977. A catalog of the Diptera of the Oriental Region. Volume III. Suborder Cyclorrhapha (excluding division Aschiza). University Press of Hawaii, Honolulu. x + 854 p.
You require "Fauna of British India Diptera: Calliphoridae" published by Today and Tomorrow publishers .Its an old fauna and a lot has changed in the field of blow fly taxonomy. But still it will provide you with basic identification. OR If you are interested you are welcome to send me your blow fly specimens and I will be happy to identify them for you.
Shall I have to send specimen photographs for the moment because otherwise I have to get quarantine certificate (which will take 3-4 months time) to courier the specimens out of the country.
