how to make an inhuman beings relatable to the audience?

so, i have this story about someone going through a rite of passage of sorts. the thing is, the the character is not human. he's actually a young humanoid cricket (and before you ask, he's not the size of a human, none of the characters in this story are). but alot of times, people may have a hard time relating to a character for how alien they look and sometimes act. it's true that his kind have different values like how your considered attractive for your chirping ability then appearance. even then he has human fears like rejection and fear of the unknown.

the thing about world i'm building is the notable lack of fully human beings. the reason for that is, well, they're giants and if a human enters this world, they become a bug person. notice how people wouldn't like that but how can i sway them to at least find my characters likable, even if they're bug people.

Could anyone capitalize the title?

Well if the character goes through something every human does, then that might do the trick.

I think a strong motivation goes a long way to make a character relatable. Even if your bug desires something that I as a human wouldn't even consider, as long as I can tell that it really wants it, I'm already empathizing with that character to some extent.

A goal, a possibility of failure, meaningful consequences of failure - you could have ambulatory rocks and still have the audience relate to them.

I've just finished watching a documentary on the DARPA Robotics Challenges of 2013/2015 and saw human audiences reacting to a robot that fell over going through the door obstacle with concern and sadness and reacting to it getting back to its feet and completing the challenge with wild elation.

The robot was not capable of feeling defeat, sadness, concern, satisfaction or anything remotely human in the circumstances and its goals were set by DARPA based on their requirements for a rescue/emergency robot, yet the humans in the audience emotionally reacted to its fall and rise as though it were a human struggling against the environment.

Set up the challenge and the consequences well enough and convey them successfully to the audience, you should have the audience relating to the characters.
