Let’s just pretend that you can see a street lamp surrounded by bugs in the picture.

Rules:

• Divide the grid into 9 non-overlapping regions of orthogonally connected cells. Fill the grid with the digits 1-9 so that each digit appears exactly once in each row, column and region.
• Each "Region sum" line is divided by region borders into multiple segments with the same sum.
• Digits separated by a black bug are in a 1:2 ratio. Not all bugs are necessarily given.
• A cell marked by a gray bug contains an odd digit if the bug is a circle, or an even digit if the bug is a square.
• The two cells marked by a diamond are adjacent to the same number of region border segments (either 0, 1, 2, 3 or 4).

Solve here.

Good Luck !

By the way, I may continue the “Bugs Like” series one day, but for now there is only one other sudoku in it, Bugs Like Pink Street Lighting - check it out !
