A note to anyone editing data quality or annotations: This specimen was alive when collected, and the data given reflect the time and place when the insect was observed alive.
Please adhere to iNat’s guidelines and do not mark this observation as “captive” or “dead”, as this causes problems for researchers attempting to find species records.
iNat's definition of a "wild" observation explicitly includes "museum/herbarium specimens that are appropriately marked with date and location of original collection". The data given are the date and location of original capture, and as such, this observation should not be marked as captive. See #5 of the observation FAQ on the forum: https://www.inaturalist.org/pages/help#captive
The "dead" annotation should only be used if the organism was dead at the time of the observation. The question of insect specimen annotations has been had on the forums, and specimens which are dead in the photo but were alive at the time of capture should be annotated as "alive", not "dead". See here for discussion:

This observation is for the cause of the deformity that presumably contributed to this black-billed magpie's death. The magpie observation is here https://www.inaturalist.org/observations/153374442
