The abdomens of female moths are much longer than those of the males - so designed, I suppose, not only for egg storage but to assist with egg laying. You can see how effective this one is at getting into those hard-to-reach areas on the trunk of this palm. Such a shame they are so beautiful!
I tend to think the fate of the palm is sealed. We lost ours last spring (amazing how quickly it deteriorated), and another seven or eight have been felled nearby in the last six months. Others were left, sick and dying, throughout the summer. And you can understand why. The cost of hiring an accredited gardener is off-putting if not unaffordable for some people. A large proportion of the cost for ours covered special déchetterie charges. I believe the chipped fronds had to be taken to one, and the trunk to another. Our local tip doesn't accept any tree trunks or roots now. No surprise, therefore, that this is happening more and more:
I fear that our towns, villages and coastal resorts will be palm free very soon, and I only hope that when these exotic moths and weevils run out of that food source, they don't turn to native plants.
