So that’s why they are called Cockchaffers!

When the temperature gets above 20 degrees Celsius the adult female matures and is ready for a bit of how’s your father. The adults will eat the soft developing grain but these guys were too busy to bother.

Where they are present they are in high numbers but very localised and rarely much further than 20 meters in to the crop.

Dimethoate seems to be the only thing that will touch them but as they are very localised, seemingly too busy to eat anything and bearing in mind that dimethoate is an OP and will take out pretty much everything else in it’s sights I thought it’s probably best to leave them to it.
