Blue Cuckoo Wasp
Blaue Goldwespe

Spider Wasps (Trypoxylon spp. --- previous two images) are the main hosts, but not the only ones, of this tiny beauty.
So when there are nests of Spider Wasps in your "Insect Hotel", you can almost be sure to find its cuckoo Trichrysis as well.

Que le temps passe vite.14 ans,presque jour pour jour,séparent cette photo prise en Juillet 2012,et cette publication en Juillet 2026.Entre Cluny et Montchanin,le Duplex 222 remonte vers Paris.Il est flagrant de constater qu'a l'époque,la végétation était encore verdoyante,contrairement a l'été 2026,qui est une véritable catastrophe,en raison de la sécheresse.

A very short video of a project to drive a small dynamo and off-hand grinder through a dog clutch using a small high speed steam engine.
Engine
Stuart Sun, a garage rescue from a rusty non-runner with a lot of faults. ¾” Bore and stroke, simple expansion, single acting. Wet sump lubrication.
Dynamo
PM Research Kit, 1.6VDC at 6000rpm. Casting kit with a pre-wound amateur.
Off-Hand Grinder
Scratch built using Proxon wheels and mini ball races.
Dog Clutch
Scratch built with Delrin chain drives to reduce friction. Step-up drive 2.5-1
Engine runs at about 2,400 rpm providing dynamo and grinder shaft speeds of about 6,000 rpm. The engine is slowed in this very short video.
