Identification e: Bee 4 - Thyreus ?
Has blue, but not really neon blue like the nitidulus (in pictures), but
lighter, more like a strong powder blue. Sometimes looks as if there is a
slight blueish tinge to the dark wings as well.
Its blue is more like the blue of the Blue spotted bee - Sp. Thyreus
caeruleopunctatus but the markings on the thorax look a bit different - at
least to me?
