Common Palmfly

[Commander]

Though some of us may have noticed the variations of the white spot and extent of the thumbprint on Common Palmflys, I was wondering if the spots/thumbprint was "season" related or some other cause.

Those who have observed or shot the Common Palmfly over the years, may want to check the EXIF data for the date/month to see if the white spot corresponds with certain months of the year, and disappears during other months.

At AH this morning, I noticed that all the Palmflys that I saw (about 6 in total) did not have any white spots at all!

Here's a shot of a more cooperative one that I shot this morning. Compare this with Neo's shot taken just yesterday. Also no white spot.

Thanks for the quick check. Doesn't seem to have a trend yet.

Just an hour. Got one 'possibility'.

After a while, I did not document the Common Palmfly anymore. There are simply too many of them (like Chocolate Pansy).

There might be a trend, but not obvious from my observations. maybe should get the inputs from the rest.
