Three-dimensionally preserved insects

Article Abstract:

The Tertiary limestones at Riversleigh, Queensland, Maryland, contain a large number of fossils of beetles, flies, and millipedes that have been three-dimensionally mineralized in calcium phosphate. The fossils are well-preserved due to the lack of scavengers and high microbial activity. They show specific details of soft tissues, especially of the eye structure in Coleoptera fossils. Some bacteria and fungi have also been preserved along with the insects. The stones containing the fossils represent a tropical rainforest's shallow pool.

Locomotor performance of insects with rudimentary wings

Article Abstract:

Wing size has little influence on aerial gliding of insects, suggesting that sailing could have preceded flying and wings could have originated from gill plates of aquatic animals through an intermediate stage that was partially aquatic. Stoneflies are the oldest morphologically for traits related to flight. A study on Allocapnia vivipara stoneflies found they cannot flap their wings to fly but they raise their wings in the presence of wind to sail over the water, indicating a possible forerunner to flight.

Insects can halve wind-turbine power

Article Abstract:

Research describing the effects of insects on wind turbine blades is presented. In particular the degree of stalling of the blades caused by contamination of the leading edges by dead insects is investigated.
