What we found, whilst Amphibian Egg Mass Monitoring, at the upper Woodland Pond of the UW Arboretum yesterday, were these lovely Odonata larvae; the larger is a dragonfly nymph and the smaller a damselfly.
Dragonflies have been on the earth for over 300 million years, and at one time had wingspans of up to 75cm!
Our modern-day dragonflies spend most of their lives as nymphs and molt 6-15 times before reaching adulthood, and this takes between two to six years.
Cool fact: 80% of a dragonfly's brain is used to process visual information; their compound eyes are huge, with almost 28,000 individual units, and they can see 360°. Plus, they are both fast and agile, with flight speeds up to 35 mph.
