basicly this, really.
just extract haven-res.jar and find file for moths in iventory (somewhere like gfx/inv/blabla cant remember

) and there u will have the name of the file u have pointers to. these pointers will then be located in haven.jar, i think (again i might be confusing em, see enders dev log regarding the highlight/show animals on minimap or as mentioned quality overlay, should be a good indicator as to exact files etc.).
however if it is in haven. jar then simply extract, search for the name of the file the pointer is pointing to ( no, rly? xD) and check how the gender is impelmented. if 2 -->1 then simply switch one of em and there u go (ofc put in new gfx in haven.res.jar). if not, please report back with findings

(most of this is pure guesses as i have never done this myself, just made some similar moding

)
