Goldenrods (Solidago sp.) are in full bloom, giving insects a welcome bonanza of pollen.
A bumblebee packs pollen into "baskets" on its hind legs. The baskets are made from long hairs.
Paper wasps (genus Polistes) also love the flowers. Some studies of goldenrod ecology suggest that these wasps may be the main pollinators of goldenrod. These wasps are normally very flighty, but on goldenrod they seem to settle down to the serious business of investigating every floret on the flower stalk.
