    47 firefly flashes in 2 minutes = how many fireflies in the back yard?

    OK
    about 70 flashes in the last 2 minutes (9:30pm)( 41.44° N, 91.46° W)
    and
    based on the spacing of the flashes, I would guess ; more than 50 fireflies
    nice to see them again

    OK, so we can assume the temp has briefly risen to 57C.

    Maybe its time to observe from indoors?

    perhaps
    I should have referred to the critters as lightning bugs?
    or, light emitting lampyridae

    No. 'Fireflies' was unambiguous.

    If 25C then per DaveC426913's info: 12/min/firefly.
    70 flashes in 2 minutes would suggest 3 fireflies, not 50.
    Well, technically I guess 3 fireflies with one of them missing a leg, or other small bodily part.
    And 47 flashes would correspond with 2 fireflies originally.
    Corresponds fairly accurately to that table.

    OK
    entertaining as the chart was
    it had zero relevance to the number of fireflies in the yard
    based on observation
    50 seems more likely===maybe more

    pesticides, light pollution, loss of habitat, fireflies are under attack
    so
    my joy at seeing them is
    well

    My bad. I presumed more precision than is warranted by those 2 decimal coords.
    They could round down or round up.
    So the precision is only to within this ~ 800m x 1200m rectangle:

    Which includes one house. Two, if we're being really generous.
