FORUM the article on jewel scarabs puts me in a position of admiring something closer my country. I thank David Hawks and Ronald Cave for illustrating the beautiful scarabs of Honduras. It must have been an ordeal to study scarabs in a Honduran forest. I'm glad there are people who appre ciate these forests and teach us about them. EDUARDO CORRALES Tegucigalpa, Honduras We were extremely disappointed in the perspective presented in the "Jewel Scarabs" article. To presume you can save endangered habitat by protecting it for others to come in and collect species for display or commerce is a misguided and fallacious concept. We would rather they stay out of the forests than promote commercial trade and accu mulation of these beetles. A great disservice has been done to the beetles by advertising the price for their lives. SUSANNE HARE AND STEVE LAWSON Tofino, British Columbia Photographerand entomologistDavid Hawks replies: I can appreciatethe sentiments expressed by Ms. Hare and Mr. Lawson. How ever, effective conservationefforts center on habitatpreservationand the health of popula tions. Harvestingbeetles at a level that cannot affect populationscan be tolerated,and in fact encouraged, if itpromotes habitatprotection in areas where protection is not guaranteed. Ask Us I have a question regarding your statement that in India and Egypt "bowls of water set into the ground froze at night as a result of cooling evaporation." I'm skeptical. BUD PARRETT Jefferson City, Montana This can happen, but only under certain con ditions. In dry desert areas that experience wide extremes of day and night temperatures, water in specially designed containersor ponds canfreeze at temperaturesjust above 32°F.On cloudless winter nights the water loses heat to the sky by thermal radiation and evaporation.In the absence of wind, convection of heatfrom the air to the water is minimized, so the heat loss through radia tion and evaporation is enough to freeze the water.
