47

Only one. If it's 42C where you live.

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

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

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

Ah, the reverse Occam's Razor!

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.



P.S. Wow. Google's Street Mappers have never been within a mile of your house...

ok
Firefly season is nearing completion
one or five females still blinking and maybe 10 males still flashing
but
almost over
female bling in the grass-shrubs-etc
males flash for a longer time and fly above the females
looking for a hookup
mostly they live underground and only come out for our enjoyment when they want to mate
better than fireworks or the drivel on tv
and
then we get to see the bats patrolling the yard feasting on other flying insects
all the entertainment needed
right here in the back yard
