It was observed that a fly used to lay eggs on the skin of Hog deer (Hyelaphus porcinus) in Kaziranga National Park, Assam, India during winter season as told by wildlife rescue operators. These larvae emerge as adult flies from the host body after few weeks. Can anyone help me in identifying the fly responsible for this infestation? Can these larvae belong to bot flies? Please find attached few images as sent to me by the rescue operators.
Some Hypoderma? Hypoderma diana attacks Cervids and is widely distributed from Europe to the Far East, Hypoderma capreola is supposed to attack Roe Deer "of the Far East" but might have other hosts as well (?).
Dear Debabrata,
on attached pictures are bot-fly larvae. Morphological identification of bot-flies could be performed on adult flies obtained from environment or on third stage larvae recovered from a host. For more details see Veterinary Parasitology written by Taylor, M.A., Coop, R.L., Wall, R.L. or Veterinary Ectoparasites - Biology, Pathology and Control written by Wall, R.L. and Shearer, D. (attached).
A lot of success in identification.

Answer by jaroslav seems correct on its a bot fly larvae. fly lays eggs in chinkara skin also in Rajasthan the best way to Identify the fly is to trap the fly. or feed the extracted larvae on fresh meat till they pupate and emerge in a netted cage.
Dear Jaroslav
Thank you so much for the response with related literature. But I would like to know on what key features did you differentiate these larvae from that of Hypoderma sp.?
Regards
Dear Debabrata,
bot-fly morphological identification is based especially on third stage larvae spiracles - see the above recommended literature.
Jaroslav
dear researcher
please send me the images from spiracle (black spot ) x10
Dear Debabrata,
in related species (Axis axis), Hypoderma diana was noted. Please use attached key. I hope it will be useful for you.
Best regards
