Aphids on a pear tree
One of many out of sight colonies,
amounting to several pounds of insects per tree

If all the insects in an acre of land chose to sit on you, they would crush you. Is that possible? How many insects are there in an acre and how much do they weigh?
To get a better perspective on the importance of insects, I set myself the task of finding out how many insects there are in any ordinary garden or field. An entomologist/gardener, Frank E. Lutz did just that more than 70 years ago.
