Couple donates bug collection worth $10m, a goldmine for researchers

Collection will help scientists piece together a large branch of insects’ family tree and be a resource for scientists who study natural controls on the environment

Insects see in much better resolution than we thought


Insects see the world much differently from us, that much is clear. For the longest time, researchers thought they are unable to see fine images due to the way their eyes are built. Most insects have compound eyes which consist of many (up to thousands) tiny lens-capped ‘eye-units’. Together, these work to create a low resolution, pixelated image.

Contrasting to that, our own eyes have a single lens, a “megapixel camera” that can actively change the lens shape according to different needs and can keep both nearby and far away objects in sharp focus, based on our different needs. The end result of our eyes is a densely-packed, high-resolution image.

DNA confirms amazing Australian isle insect not extinct after all


When black rats invaded Lord Howe Island after the 1918 wreck of the steamship Makambo, they wiped out numerous native species on the small Australian isle in the Tasman Sea including a big, flightless insect that resembled a stick.

But the Lord Howe Island stick insect, once declared extinct, still lives. Scientists said on Thursday DNA analysis of museum specimens of the bug and a similar-looking one from an inhospitable volcanic outcrop called Ball's Pyramid 14 miles (23 km) away confirmed they are the same species. The finding could help pave the way for its reintroduction in the coming years.
