I had to go thru my widestripe hatchlings from this year,
and last year
many look quite similar in overall pattern expression
The head pattern of my crimson miami mot is just like yours
Many of the w/s babies have the same pattern distortion you are calling 'zigzag'
I do not think it is zigzag
or,
it is "aztec influence" maybe?
Widestripe seems to dominate other patterns
with the exception of tessera
The hatchling it is definitely widestripe
That's the best I can do.
Will you be raising the babies up for F2 project?
