237 Bubley, Standard Oil Co. of N. J. Mosquitoes Refuse to Lay Eggs Unless Fed on Blood; the Scientist Obliges Multiple bites are the price F. C. Nelson pays for raising pests to aid Esso Standard Oil laboratory's experiments with insecticides near Elizabeth, New Jersey. Glass dishes contain larvae and pupae. The almost microscopic eggs are covered with a bit of froth. They lie dormant through the winter and hatch a new generation of caterpillars in spring just as fresh leaves are sprouting to provide the youngsters with plentiful food. The hungry tussock and other specimens from no farther afield than our Manhattan garden provided a good nucleus for my gallery of insect Kodachromes. Then I started look ing about for more. At first it seemed a bit foolish for a city dweller to select insects as a photographic sub ject. The task was going to take at least all summer, and for a while I considered moving to some nice rural spot in the South. Then I learned that entomologists had found and described more than 15,000 species, repre senting almost every known family of insects, in the State of New York alone. Why go far away, with so copious a supply within easy reach? To supplement my back-yard source, I ventured across the Hudson River, over into the garden counties of New Jersey. Here, thanks to modern science, I was disappointed; insect collecting was about as fruitful as it would have been in Times Square. The care fully sprayed cornfields, cabbage patches, and flower gardens of New Jersey may be the farm er's and gardener's delight, but they are the bug collector's despair.
