At this time of the year, the female hummingbirds are in the process of nesting and raising their young. With young, their diet changes more to bugs rather than sugar water to provide the needed protein. Once the young are on their own, the female will appear at the feeders more often.
There is not a family sharing of effort among hummingbirds. Except for a brief mating encounter, the female hummingbird conducts the nest building, incubation and young rearing by herself.
A hummingbird's diet is about 80% soft bodied flying bugs and spiders, the sugar water gives them the energy to chase them down. Just before and after migration, they are busy adding weight and will be at the feeders more often.
Ahhh...imagining that irresistible "new car" smell?
