In the book Insects: Their Natural History and Diversity, ISBN-13:978-1-55297-900-6, prof Stephen Marshall tells us beetles are found almost everywhere in the world and range in size from 0.25 mm up to 20 cm, a range equal to that between the tiniest shrew and the largest whale.
Beetles can be mightily destructive (Emerald Ash Borer), great cleaner-uppers (Carrion Beetles) or just simply beautiful as they go about the business of living, growing and reproducing.
My keyword searchable website inclues includes 33 galleries of beetle photos, all available in high resolution for educational, editorial, corporate and advertising uses.
When you need images of beetles, please have a look. If you are a photo researcher and wouild like to be able to download 600 pixel files for review and comping, without charge, just let me know by email. I'll be pleased provide that access.
