One of the Swallowtail (think Western Tiger ) eggs is whitish , so hope it hatched and so far well.
Looked for the little caterpillar (think thats an instar(?)), so far not luck. The other egg is still green. Wonder why the butterfly left them on a Peach( o Almond ) tree seedling in a pot on patio. Read they're foodplant are Willow, Birch, Hollyleaf Cherry, Sycamore, Poplar and Alder. Also wonder if same type of butterfly of caterpillars found on wild grape in yard. Were SO tiny, brownish and looked like a giant eye .
