This huge branch, which was rotten at its core, just could not cope with the weight of water-soaked Basket Ferns and came crashing to the ground during the day.
As you can see, it was right in front of the light sheet! This would have been a major catastrophe, for me, had I been standing there at the time. No additional damage was done. I could find no insects of any kind amongst the foliage as I dismembered the fallen limb. Pity.
