By golly, this is a strange time for Pandora moths to pop out of the woodwork& er& soil. They were here in grand numbers back in 2017, and it9s usually five to 10 years before they appear again. Must be climate change; something is taking place in and around us that is favorable to this species. And another species is on the rampage. Over on Green Ridge, near Sisters, white satin moths are defoliating the aspen trees and the adults make it appear as though it is snowing in July. In past times, pandora moths were known as a for- est pest, defoliating pines about every 20 years 4 which ruined the attempts of foresters to grow pine timber for lumber. But the native peoples of this region looked at them very differently; they har- vested, stored and ate the lar- vae of these delicious moths, and as far as I know, some families still do it to this day. The larvae were collected just before they were ready to pupate, before they began their July migration from the high green boughs to the for- est floor to pupate in the soil. They were/are gathered by hand once or twice a day, and temporarily stored in trenches in the ground. The larvae were then roasted in fire-heated sand for 30 minutes; the sand not only cooked the insects but also served to remove the fine hairs 4 setae 4 from their bodies. The cooked larvae were/ are then washed, sorted, and dried. Stored in a cool and dry place, they keep for at least a year and perhaps as long as two. The dried larvae 4 known as piuga 4 are reconstituted before consumption by boiling for about an hour in plain or salted water. I9ve heard the boiled insects have an aroma described as that of cooked mushrooms and are eaten as a finger-food; the entire larva is eaten except for the head. (This reminds me that big brown bats who come here in summer and eat our Jerusalem crickets don9t eat the heads either.) The cook- ing water is also consumed as broth, or used as a base for a piuga-and-vegetable stew. Yum, yum& This also reminds me of the time I spent living with an aborigine family on a billabong near Darwin, Australia, years ago. My host9s 14-year-old daughter Daphne teased me as she was chomping down on the roasted wood-boring beetle larvae she dug out of the eucalyptus. I still get a funny feeling in my tummy think- ing back on those interesting times. So& back to our own pandora moth larvae. I don9t know if you ever gave any thought to the process of metamorphosis 4 when the larva builds the outer shell it will change inside from a wiggly caterpillar to an adult insect that has the ability to fly and mate. (In butterflies, the shell is known as a chrys- alis, and in moths, a cocoon). The adults emerge and then as they age their cal- endar of life triggers the recognition of sex, and the females begin to put off a perfume that today is known as a pheromone. Wikipedia says a pher- omone is a secreted or excreted chemical factor that triggers a social response in members of the same spe- cies. Pheromones are chemi- cals capable of acting like hormones outside the body of the secreting individual, to impact the behavior of the receiving individuals. In fact, adult male moths go nuts over it, and can sense it from several miles away, especially if there9s a breeze Bring in this coupon for $2 OFF $1 OFF or any 16-20 lb. bag of Cat Food any 30-35-40 lb. bag of Dog Food 102 E.

Way back, when I was a kid on my grandfather9s farm on Jones Hill Road in West Haven, Connecticut, I woke up one summer night in the upstairs bedroom to the sound of soft thumping on the screen of the open window. I discovered a cecropia moth outside acting like it wanted to come in the bed- room. I went and woke up my Uncle Ben, the naturalist of my three uncles, and told him about the moth. He rubbed his eyes, blinked and, throwing the sheet off himself said,
