Microflyers are diverse, small, minute, flying animals from Darwin IV. Along with their plant counterparts, the abundant and varied aerophytes, these creatures can, at times, darken the sky with their numbers.
These minute, airborne animals travel in clouds (luminous at night). The tiny creatures are consumed in prodigious numbers by Darwin IV's placid air-sifters like flipsticks and keeled grove-backs, and possibly also stripewings. Born pregnant, these microflyers complete their lifecycles as eggs in the excreta of the animals that eat them.
The Grove-back’s rare emergence rom the loamy soil and subsequent feeding coincides with the equally infrequent, periodic expansion of the microflyer swarms.
