cantaloupe melon f1 sweetheart pollination ?

good morning all

i am growing these melons in the greenhouse at the mo and this morning i have noticed 1 flower :thumb:

now any ideas what to do with this one flower :confused:

its does say on the packet that i have to insert the male flower into the female :eek:

has anyone tryed these before and do i have to do that or will the fruit come on its own as the doors are open all day to buzzy bees

another thing thats worring me is what happens if that one flower dies off before another shows up :confused:

as you can tell this is my first year growing these:D

i have also moved them as they were next to my cucs and i have read something about cross pollination :eek:
