when to stop

my google searches always start
with something innocuous
like a hovering bee?
that identifies the hoverfly

that leads to admiration
for its batesian mimicry
of bees and wasps
with body of banded
black and yellow

and appreciation for
its pollinating habits
and skillful wings
constantly adjusting to wind
to hover in place

but then I follow links
for words like myiasis
before stopping
and being thankful
that the lovely hoverfly
has flown off
to hopefully
pollinate some flowers
and not lay eggs
