Cold Destroys Lcpidoptera — Larvae and 

 Eggs in South Florida 



By Dr. George Mott, Marco, Florida 



I came here February first hoping to have a good 

 spring and summer's work collecting lepidoptera, lo- 

 cating in the most extensive orange and grape fruit 

 grove in this section. On the nights of the third and 

 fourth we had frost severe enough to kill all garden 

 truck and all blooming as well as most of the grow- 

 ing wild flower plants. 



The grove is on a tide-water creek, fringed with 

 mangrove and other sabine soil-growing shrubs and 

 vines, looking like an ideal spot to trap heterocera 

 (moths). I built a trap using an excellent gasoline 

 lantern for light. I kept it lighted every night, until 

 a gallon of gas was used, without capturing moths 

 valuable enough to pay postage on themselves, to the 

 third zone. 



I went out every day, except Sunday, with the net, 

 chasing butterflies, and to date have taken some twen- 

 ty species, and of some of these only a few specimens. 

 Am just beginning to find a few^ larvae. The new 

 growth of cum'uhi'ulus legumes and many nocturnal 

 blooming plants is just beginning to show a few 

 blossoms. I will set traps again as soon as dark nights 

 come. 



I attribute my poor success to the fact that the 

 cold snap destroyed both larvae and eggs of insects, 

 also the food plants so that the eggs of those mature 

 insects that survived the cold perished of inanition 

 early in the second stage of their existence.
