Great for schools! Its nice to get feedback! A reed stem containing a Osmia bicornis nest with brood cells was taken from an artificial stack at a grassland site near the Biocenter of the University of Würzburg, Germany (Latitude 49° 46' 47.78, Longitude 9° 58' 22.55) in October 2012, few weeks before hibernation of Osmia was initiated. bicornis lacks the CYP9Q subfamily of P450s but, despite this, exhibits low acute toxicity to the N -cyanoamidine neonicotinoid thiacloprid.

What type of nest box do you have Caroline? When the larvae are fully grown having consumed all the food provisions and just prior to entering the next stage in their life, they defecate, allowing their bodies to be free from any waste products that has the potential to cause problems before they enter the next stage of their life.
