A little green beetle on the back of the house
I don't know how to look at photo here and see what settings a person used to get the shot they have. So could you or someone tell be what gives this near white outline on the little bug.

At first I thought it was an artifact introduced while sharpening, but when I went back to the Raw image, the white outline was there. I couldn't say why that is. Anyone have an idea as to what it may be?
Setting were 50mms F 3.5 ISO 200 1/320.

Happens naturally along edges of high contrast, because you are turning an organic shape into square pixels. how to make a diagonal hard edge shape out of a series of tiny square blocks. Those along the edge have a challenge to overcome that is not noticeable zoomed out. Called anti-aliasing. Note at actual- un-zoomed view - you have a tidy transition... nice and crisp. The anti-aliasing is doing its job perfectly. Note that this also appears in the beetles back and even along highlights in brick, your eye sees them as a glistening highlight- unable to pick out the individual pixels- till you go an zoom in about 1000% LOL/
Often, there is a colored fringe on a channel. If you open lightroom, you will see under lens correction, Defringe... not sure if it will take this out-may ruin the effect. Note that when printed or viewed at final size, you won't notice it at all, in fact it is necessary to get the effect you want of the highly reflective bugs shell.
