Are honeysuckles good for wildlife?
Yes, honeysuckles and especially the many forms Lonicera periclymenum, are good for wildlife for a number of reasons.
The flowers attract pollinators including moths and especially the large, night flying hawk moths. Those with smaller flowers attract bees and other insects. The berries that follow later in the season are eaten by many fruit-eating birds and the tangled growth also provides sheltered nest sites. Before spring or summer pruning, be sure to check that there are no nests with eggs or fledglings.
Towards the base of older branches of climbing varieties, the bark naturally peels off into thin strips and some birds pull it away to use as nest building material.
