New-word Day

New-word Day
I figure it's a good day when you learn a new word.

Halteres. I didn't know what they were until I noticed the little paddles on the sides of this dandy-longlegs walking about on our kitchen ceiling today. (We brought the cat's grass box back inside and a couple of dandy-longlegs a week emerge. The cat appreciates us for doing so.)

Halteres (singular 'haltere' and apparently both pronounced three-syllabically at least in traditional Biology-talk) are the evolutionary result of a pair of wings not being needed precisely as the other pair were. So they became like really smart stablisers.

Annalia S., Steve Bucknell have particularly liked this photo

‘The critical role of the haltere in flight stability was first identified in 1714 by William Derham, who showed that a fly could not remain airborne if its tiny halteres were surgically removed.’

William Dereham well worth looking up in Wiki: a remarkable mam!

An excellent photo, to show the complex, beautiful structures of this fly.

Thanks, Steve. And I *will* check out Derham's story.
