There were several males at the same location.
This red female was a foot away from a male and a green female Silver Wisp. I have observed this at some other locations too, that there are red and green females with the males
There were quite a few of them around, some females were red like this one, others were green

I gather this must be a very young male, as 99 % of the Silver Wisps I have seen are white-silver
