What do you like about this subject?

Insects and related creatures are so diverse that it is impossible to become bored learning about them; and there is a great deal left to be discovered about them.

What do you still hope to achieve/learn in this field?

I am a writer/illustrator, and hope to publish more books and articles on natural history, especially insects and spiders.

Something interesting about this subject that others may not know:

You share over 20% of your DNA with common "fruit flies," genus Drosophila. You like bananas?:-)

Something controversial or provocative about this subject

Chemical insecticides do more harm than good in most cases. Returning agriculture to a smaller scale (largely doing away with agri-BUSINESS), would solve many pest problems without chemicals.
