Interesting post re turtles and female ‘midges’ that require blood supplying host for reproduction.

“Female midges need blood for protein to produce eggs; males eat flower nectar. To our knowledge, we do not have any biting midges at Hilton Pond that attack humans (or mammals in general?), so the insects on the turtles may be a large midge species that specifically needs reptiles as blood hosts.”  Yellowbelly Slider Turtles and Midges
