Gardening: pumpkins: male and female flowers

Self-tutoring about gardening: the tutor mentions the trend of male, then female, flowers on pumpkin plants.

I heard, and it’s also been my experience, that with pumpkin plants, only male flowers will be produced for awhile, with female ones eventually to follow. Why might pumpkin plants adopt such a trend?

An idea I imagined – and now I’ve read elsewhere – is that the pumpkin plants want to attract pollinators – insects and even birds. The big showy male flowers, with their pollen inside, invite pollinators, who will develop the habit of visiting. Therefore, when the female flowers do open, the pollinators will already be around, so pollination will be virtually certain.
