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.

2016-10-16 Spider identification:

Hi, Allison:    Thank you for including the nice, clear images with your question; and thank you for taking such good care of your little neighbors. :-)    The spider is an orb weaver, probably the Cat-faced

2016-10-15 Phidippus Apacheanus?:

Hi, Lisa:    Wow, what great shots!  I think you are right.  Looks like a female Phidippus apacheanus.    If you are on Facebook, I have a group called "Arthropods Colorado" there.  Would love to

2016-10-14 what is this bug?:

Hi, Jeff:    Thank you for including the images with your question....    No, it is NOT a bed bug.  It is a beetle, and from the looks of it probably a "minute brown scavenger beetle," family Latridiidae

2016-10-12 weevils:

Cindy:    Without seeing at least an image, and preferably specimens, I cannot positively identify the insect in question, let alone advise how to control it.    That said, insects like you describe are
