Obs Date of dead insects

Today, someone submitted two observations of dead insects. The photos could very well have been taken today but the insects have been dead for some time as neither of the species would be flying yet this year in Ontario. I have flagged both records as “dead” in the annotations but they are still “research grade”. Given that these data could be used to generate flight periods, etc. this would result in inaccurate data. It would be nice to somehow make these records “casual” but I’m not sure what the appropriate method of doing so is. Flagging the date as inaccurate?
