Update from Wellesbourne

Monday's sampling produced the follwoing counts:

• 12 carrot flies (3 traps) - the second generation appears to be even more delayed than predicted - perhaps there has been some significant pupal aestivation due to the high soil temperatures recently.
• 12 cabbage root fly eggs (15 plants) - probably signals the end of the second generation.
• 11 bean seed flies (3 traps)
• 29 pollen beetles, 9 flea beetles, 7 small white butterflies, 4 large white butterflies (3 traps)
• 18 silver Y moths (2 traps) - suggesting a recent influx of migrants
