On July 30, when I was lamenting about no seed setting on Ebenus cretica, Alice told me about Carpenter Bees. One of the neighbouring plants which had been bombarded by pollinating insects was a Dorycnium hirsutum, and a principal bombadier was the Carpenter Bee. Yesterday I was cutting back dead wood from the Dorycnium, thinking that the drought had taken its toll, when, at the base of the dying stems I came across individual great fat white larvae eating their heads off until they almost filled the interior of the stem. Maybe these are the other part of the circle of the lifecycle of Carpenters.
So my net result is no Ebenus seed, but the plant is responding well to the recent rain, plenty of Dorycnium seed seems to have been set, but the plant is finished.
