"Under laboratory conditions, individuals return to the same nesting sites, but exactly how they navigate is unknown."
I can tell you that we have had these sleeping in the ledge under the top of our windows every spring/summer for the past two years. One has just come back for the first time this year - it sleeps there all day and leaves at around 6pm. Of course, I have no way of knowing whether it is always the same one!
My question is - how do I try to 'relocate' my guest? I tend to not want to interfere with nature, but I also want to leave my windows open without fear of having the katydid coming in and nesting.
