I've only noticed it in the evening, but it may be morning or even after
noon as I've been on Vacation and have only noticed since I've returned.
I've not had much time to spend with them.
 
Yes, it has been very hot until yesterday.  I did not get a chance to look
at them today or tonight becuase of work and church.
 
Thanks for the input, that is what I suspected but I am a "newbee"
