Not just two large compound eyes but three more smaller eyes in the triangle on top of the head - which are used as light sensors (which way up am I flying? where is the horizon?) enable me to fly in the dusk.
Two very thin short antennae act as wind direction and wind speed detectors. A masterpiece of engineering.
Thanks for the ponds over there - and the rough debris - without them I would not be here....I'll be off soon to catch some assorted gnats and midges. Another photo on Hills Farm Wildlife.
