Moved from ID Request.

ID of this Butterfly 🦋
Yes, like a Giant Swallowtail (Papilio cresphontes).

 
BG also recognizes Western Giant Swallowtail.
which occurs in Texas. I am unable to separate from Eastern based on appearance so hopefully someone familiar with these species will ID.https://bugguide.net/node/view/1028443/bgimage

 
The spots
Good eye! Aren't the spots on the Western more crescent shaped.

 
Not my area of expertise but the head and neck spots are used
to separate these species https://bugguide.net/node/view/1028444The head and neck spot band favors Western for this image.

 
Excellent...
