Okay thanks I just added excretory... I am now trying to find others.I'm not sure where excretory would fall in those categories, but you should know it...just a general question, where are the "ears" of insects? This was on my test and I wasn't sure because I know grasshoppers have them on their legs, but it asked about all insects...and it asked for a specific name, which I wasn't sure of? We ended up putting the antenna on the head because we didn't know.
I would've just write that they have them on the legs??
The hearing organs are called "tympanum"
Oh thanks!! And yeah, circulatory is a must!
