The aphids on the tropical have just exploded in the past week and the
plant is covered with them. What can I use to kill them without harming
the butterflies? Soap? Half-strength dormant oil spray?

for one plant, soft brush them off or use a
spray of water, see if any remain after that
and then hit them with a weak soapy water solution
to drown them. keep an eye out for ants that may
be "herding" them. repeat as needed...
