How does the emergence timing of a cuckoo bumblebee queen typically compare to that of her host queen?

Answer

She typically emerges later in the season

Cuckoo queens emerge later than their hosts to ensure the host colony is well-established, has raised a substantial worker force, and can provide continuous feeding for the parasitic larvae during the latter half of the summer.
