The black butterfly looks like a Pipevine Swallowtail. Pretty! Last year really was a big year for the Red Admiral! Mild winters with enough rain to encourage fresh nettles (host plants) is good. My nettles are just now putting out new growth, but last year it was looking good by this time. Some Red Admirals overwinter as adults in mild climates, so that butterfly could be getting a bit old...or maybe it just hasn't had enough food to recover yet. BTW, they prefer very overripe fruit. Maybe the strawberry isn't old enough to tempt it yet!
