The Lepidopterists' News THE MONTHLY NEWSLETTER OF THE LEPIDOPTERISTS' SOCIETY p, O. Box 104, Cambridge 38, Massachusetts . • Edited by C. L. REMINGTON and H. K. CLENCH Vol. I, No. 8 December, 1947 This, the last number of Volume I, is devoted substantially to the first annual Season Summary of Lepidoptera in North America. The re gion was divided into eight fairly uniform faunistic areas, for each of which a ge-neral sunmary was compiled. This year five of ·the eight were sU.mmarized by an individual member within the area. In aucceeding years it is planned to have all areas so treated. In all, 43 different members participated in the reports. These ar.e listed at the end of each area sunmary. Of course: each of the five signed compilers provided a large share of material for the report for his area. All areas were represented, but a particularly weak response from the Southeast and Central areas decreased the significance of sum maries #5 and #6. Area #1 was the most completely covered. This year three members collected extensively in the Far North and ·two reports, covering well ... separated sections,' make that area probably better cover ed this year than usual. Certain important gaps appear in·thls ~aar.ts record, with the following sections missing and needing attention: Nev ada, New MeXico, Idaho, Montana, the Canadian Far dVest, most of Texas, Oklahoma, Nebraska and the Dakotas, the entire 'Southeast, except Flor ida and Virginia, Minnesota, Wisconsin, OntariO, eastern Michigan, Iowa, most of Ohio and Pennsylvania, and Newfoundland. Eventually we hope ·to extend the surrunaries through Mexico. A very noticeable lack of moth records shows up in a perusal of the following pages. It is hoped that moth records will be at lea'st as numerous as those for butterflies next year, since the moths comprise a vastly larger group of the Lepidoptera. This year some members were caught unawares or given too little advance notice of the Summary.. Also, records had to be of a rath~r ran dom nature and in some cases based on memory. Future participants are earnestly urged to begin keeping simple notes throughout· the collecting season, with exact dates noted so that a basis for accurate comparison may be obtained after a few years and the records of the Summary may gain in value. The ' next Summary is planned as a supplemep.t to the NEWS, with allowance for at least twice as much material as this year. In these summaries an effort has been made to use up.to-date no menclature (Limenltis, not Basllarchia or Heterchroaj Speyeria, not Ar f,ynnisj Boloria, not Brenthis; Minai!!, not Cercyonis or satlrus; SphInx; not Ryloicus; etc.). Most subspeclfic names have been omIt ed since ·in all American cases known to us the races are geographtc. The NEXIS does not use Latin names for varieties, forms, or aberrations. Authorities' names are not considered necessary for this sort of project and have been deliberately omltted~ -87- FmLD SUUMARY OF LEPIDOPTERA .. 1947 SEASON 1. SOUTIDVEST- CALIFORNIA, ARIZONA, 'NEVADA by Lloyd M. Ma.rt in The early fall rains of 1946 caused many ot the early speeies of butterflies to emerge ahead of schedule in cel.·tain localities in the Southwest. Lycaenopsis Eseudargiolus echo wafl reported as early as Dec. 17, 1946, In La Tuna Canyon, Los.Angeles Co., with Incisa11a lro ides out at El Cajon on Jan. 26 and with Melitaea wright11, which Us'U arry appears in April, being taken on Feb. 241~~ny specIes of moths that normally appear much later in the season came out very early and were gone by the first of Febru~ry. From Janll_ 1 to the present ' day nas been the driest year in 64 years here in soutllern California with less than :3 inches of rain for most sections that hormally have' 15 to 20 inches. This long dry spell caused many 01" the local species that are usually common to hold over, possibly until nf~xt year, or until we get more rain. ' 13auer found Hemileuca nev~densis' (~ommon at Riverside Nov.4. In the desert, Melltaea neumogeni, Anthoearis cethura, and Euchloe creusa had a short, very early flight in late February. From late March through April very few of the deser.t species ()f butterflies, which are usually out in 'good numbers, appeared to any c~xtent. In Mint Canyon the day-flying moths appeared in early March. Annaphila dlvlnula, ' ~. thothrlx neumogeni, Melicle tera EulcheriEenn~, Wisocnemls Erorupta, and Euproser~lnus Ehae on mo ave were more abundan than usual (Evans). Heid ,found te October deser collecting poor ' because of unusual dry ness. Melltaea chara, Danaus strigosa, Hemiargus ~ i ' ~rephidlum ex ilis, and PholIsora libya were fairly common In wasnes, and one Apoaem- ia palmeri wa~ fQ....'Und. ~_ __ . ~~ -- Polygonus 8.mITtas .,arizonens'is wS:'s taken in Presidi.o Park, San Die go, by several co lectors in unusual numbers In September. Also an un usual number of Py~gus xanthus was taken durlr~ the season. Both of these are rare in collections. "Tharsalea hermes was much below normal at average date" (Thorne). Poanes melane. a recent arrival in San Dle eo Co., has become one of the commonest sklppE~rs in the county. Habro dais ~runus was extremely common throughout August allover the S. Cal- i!orn aMEs. ", In general. the collecting conditions weI'e very poor in the moun tain regions of California, though in some loealities some good reports came ,in from late collecting. The High Sierras yielded Parnassius beh !il, Melitaea malcolmi, Lycaena cupreus, and l)a iliO indra, in the earlY part of August. ' The Spe¥erla were not out as p1 entlfully as usual, but several 'good species were taken in small numbElrs. Oeneis chryxus stani slaus was common on July 4. o. chryxus lvallda and EUphydryas sIerra i were scarce and two weeks early. sat¥rium fu11ginosa, Lycaena hetero- ~~ and Me-litaea hoffmanni all had a good year. ' In northern California, GlaucoPsfche ~Lamus behrii and Plebeius maricopa emerged about a month later han usual. -Colla& occlden~al s chrysomelas and Euphydryas editha rubicunda sElemed to be faIrly plenti ful, but were two weeks earlYeApodemia mormo langei was out in good numbers near Antioch, both males and females 'being taken at the normal date. E. editha bayensis was unusually rare, (continued on next page) . Ii ;,- . , " ,. 1. S.OUTHWES~- cont, Southern Arizona also lacked its normal amount of rain. However, moth collecting was very good. Seve'ral very rare species were taken, such as, Arctonotus terlootii, Bertholdia tri~ona, Gerrodes lon~, Charadra pata, Euchaetias antica and Sphinx oIrii australia. ~ar, 250 species of butterflies and moths nave been determIned From the many thousands of specimens collected in Madera Canyon, santa Rita I~s., Ar izona. \Vhen the material is all determined the number of species from this one locality will come close to 60'0. Around Yuma and the Gila r~s. in Arizona Bauer took several good species. Papilio rudkini and its forms have definitely been esUIDli&wd. Anthocharis Rima (which was absent in 1946) was flying in considerable numbers all t rough February. The majority of spring species were out in numbers, though some that have been taken in the past did not appear. Melitaea dymas, though absent in spring; was common in late summer. The migrants, Danaus plexippus, Libythea bac,rupanii and Vanessa cardui, arriv ed earlier than usual. " Anthanassa texana was taken for the fIrst time at Yuma. Bauer found the-larvae of""H6niII"euca j1;no ttabo\lt 75% infested with two kinds of parasitic 'flies and ?ne wasp. Only one report came in from Nevada. Hammer spent June 13th at Lehman Caves in hopes of getting Euphydryas nubigena lehmani but not one specimen was seen., Aglais milbertl and Plebejus saetiOl\ls were fresh and common, They reported the country very dry, w Ich generally should produce many good species of butt'erflfes and moths. , Contributors;- -- .' - - - D.L.- - ,- Bauer,- - - J.L.-- -Creelman,-- -- -T.W,- - Davies,- - - --- W.H. -Evans,. - - W.A.- - - Hammer, Graham He$d, R.T., Reeves, C.L.

MISCELLANEOUS NOTES Eugene Monroe, of Macdonald College, Q.uebec, spent the last two weeks of July collecting at LAC A LA TORTUE, near Grand Mere, Champlain Co" Que., an exceptionally interesting locality in the sandy portion of the st. Lawrence Valley with a special flora and fauna. He took o~ 7000 moths in ten nights (only half of which were really favorable), • Included were: Fagltana littera" Syneda alIeni, Syngrapha hochenwarthii, Polychrysia formosa, capis curvata, Acossus centerensls, Apantesis wl1- liam~Ii" Lexis bicolor" Eubaphe laet,a, HetIalus gracilis., Sthenopls qua.. dr:t&uttata, etc~ SpRing,ids were common a light" esp.

Monroe, commenting on the Gaspe trip in August (see p.58)" consi- ders that trip too late for st. lygdamus cou~eri. "In the southern Lau rentians, ' this species flies in late May'an early June; in the Lauren tide Park it appears later in June. It was abundant in a coll~ction from Bic, Rimouski 'Co., ~ue., made in' early July. The date of appear ance in this region appeared to be slightly ahead of Plebejus saepiolus.' -89- 2.
