- The tower crane is build on sections of steel structures from ground level, they build much higher than needed, so the protuding section at the top that houses the crane do not need to be removed all the times, that probably explains the cost of building. They probably start to remove the protuding section when it reaches a height which is easy for machinery to access.

If you want to identify exactly what they are capture some and take them to you County Extension agent and he/she will be able to tell you what they are and if they pose a danger to you and your family.

- Q: It affects my day to day life, especially in the summer, having to cope with crane flies, wasps and moths getting into my house, so I usually just pretty much keep myself in my room, door closed, windows closed to prevent any from getting into my room.

If my room is too hot, I'll just sit in the dark with the window slightly open, in fear of them coming into my room. It's getting silly now and a lot of my friends will tease me about it. Really it's weird, I'm afraid of these insects, however I don't mind spiders (though I will not touch them), or any other insects for that matter. Can anyone help me to overcome my fears?
