I sent these backyard photos to a few computer vision tools with results ranging from wrong to interesting.  I also asked questions using a conversational search engine about the size of male mason bees.
 

iPhone Visual Look Up is for identifying all objects (food, objects and living things too) in photos and videos on the iPhone.  For these photos Visual Look Up produced wrong or slightly wrong answers - Western Honey Bee and Osmia Rufa.

iNaturalist is for recording observations of individual living things, particularly things that can be tied to a species name.  iNat uses photos with a date, location, and crowdsourced identification. iNat's response to the last photo was Genus Osmia (139 native species of mason bee in North America). 

Perplexity AI is a conversational search engine that answers queries using natural language predictive text.  Perplexity's response to, "Are male mason bees smaller or larger than female mason bees?"  Click on the small numbers that link the response to a reference.

Male mason bees are smaller than female mason bees. Females are larger than males, with shorter, thicker antennae. Mason bees are generally much smaller than honey bees or bumblebees, measuring only about 1/4 inch long1

This size difference is a notable characteristic of mason bees, with males being noticeably smaller than females, typically around 7-15 millimeters long in most North American species3
