I really thought that it was a moth because of its size and pale shade of colors but to distinguish accurately the curious feature of this species is that butterflies has different colorful patterns on their wings that folds vertically side ward. From details of photos below, you can see how they hold their wings vertically while pollinating the flower.
There are many different species in the garden mostly tiny-like creatures usually found in the backyard and others generally found on neglected plants. Flowers here particularly to be damaged because of their presence as they are considered as garden pests too. I don’t have enough time to drive all these insects, nature will soon eliminate them and disappear. Particular attention for butterflies as frequent visitors, they come on the same time to pollinate the flowers, definitely it’s a great asset for the day!
