Overnight garden visitor

A really impressive dragonfly perched itself on one of my rose bushes yesterday evening.    I didn't think to take a photograph of it at the time, but when it was in the same spot this morning I couldn't resist.  Any insect that eats mosquitos is very appreciated in the garden, so here is my photographic salute to this welcome visitor.  After taking the first photo, I used a ruler to get a rough measurement of it, and the ruler's proximity caused the dragonfly to scoot up the rose bloom about half an inch.  So, this beautiful insect measures in at a wingspan of three inches.
