Out of curiosity, I asked Copilot for its opinion:
In chess, are the Epaulette Mate, Dovetail Mate and Swallowtail Mate based on a similar pattern?
Short answer: Yes — Epaulette Mate, Dovetail Mate, and Swallowtail Mate all belong to the same geometric family of mating patterns: king‑restriction mates, where the king is trapped by its own pieces in a characteristic shape and the attacker delivers mate with a single heavy piece (usually a queen).
They are siblings, not identical twins. Each pattern is defined by a different cage geometry around the king.
♜ Core Takeaway All three mates share the same underlying motif: The defending king is immobilized by its own pieces forming a geometric “cage,” and the attacker delivers mate with a queen (or rook) exploiting that self‑block.
Where they differ is the shape of the cage.
♜ What Unifies Them All three are:
Self‑block mates (the defender’s own pieces trap the king).
Queen-delivered mates (almost always).
One‑move mating nets once the geometry is present.
Back‑rank or near‑back‑rank patterns.
Members of the same motif family: “Geometric restriction mates.”
This family also includes [more “roses”]:
Corridor mate Box mate Coffin mate Guillotine mate Epaulette / Dovetail / Swallowtail as the three “shape‑based” subtypes.
The kill box mate is delivered by a rook, with support of the queen. The rook is on a square adjacent to the opponent king with the queen one square away from the rook on the same diagonal. Together the queen and rook form a 3 by 3 box. The opponent king is often mated against the edge of the board, although this mate can also be applied away from the edge of the board where other pieces prevent the escape of the king.

There are three types of walls of the killbox.

-squares covered by attacking pieces

Btw, there is a specific killbox mate too, if I'm not mistaken.
You are correct.

Kill Box Mate
The kill box mate is delivered by a rook, with support of the queen. The rook is on a square adjacent to the opponent king with the queen one square away from the rook on the same diagonal. Together the queen and rook form a 3 by 3 box. The opponent king is often mated against the edge of the board, although this mate can also be applied away from the edge of the board where other pieces prevent the escape of the king.

The dovetail and the swallowtail are the most common when the king is mated in the middle of the board. They differ 45°
