As there is very little winged life this month, and the larvae have nearly all sought out their winter quarters, special attention may be given to pupae. The earlier this work is started after the insects have completed their change the better. If left late, many pupae will have been destroyed by floods, moles, &c., and a prolonged series of frosty days may render digging unproductive if not impossible. Again, it must be remembered that some larvae are not yet down, and by digging at the roots of the trees on which they are feeding, you are preparing an acceptable bed for the late species, for the pupae of which you may call again in about a month. Larvae may be obtained by beating and searching as before, but this work should be done as early in the month as possible, since but few are feeding after the first week or so. Butterfly catching is now practically over, only a few of the late species and the hybernators being on the wing, and these only on mild days. _Noctuae_ are still attracted by sugar and ivy blossom, and a few may be found at rest. _Geometrae_ and Micros may be taken from palings and tree trunks by day, or caught flying at dusk. The imagines of October may include the following butterflies: Brimstone (_Rhamni_) Pale Clouded Yellow (_Hyale_) Clouded Yellow (_Edusa_) Comma (_C-Album_) Large Tortoiseshell (_Polychloros_) Small Tortoiseshell (_Urticae_) Peacock (_Io_) Camberwell Beauty (_Antiopa_) Red Admiral (_Atalanta_) Painted Lady (_Cardui_) Small Copper (_Phl[oe]as_) And a few late 'Blues.' The principal moths of the month are: =Sphinges.= Death's-head Hawk (_Atropos_) =Bombyces.= Plumed Prominent (_Plumigera_) =Noctuae.= Large Wainscot (_Lutosa_) Red-lined Quaker (_Lota_) Yellow-lined Quaker (_Macilenta_) Beaded Chestnut (_Pistacina_) Brown-spot Pinion (_Litura_) Chestnut (_Vaccinii_) Dark Chestnut (_Spadicea_) Red-headed Chestnut (_Erythrocephala_) Satellite (_Satellitia_) Dotted Chestnut (_Rubiginea_) Orange Upperwing (_Croceago_) Brick (_Circellaris_) Brindled Ochre (_Templi_) Green Brindled Crescent (_Oxyacanthae_) Marvel-du-jour (_Aprilina_) Angle Shades (_Meticulosa_) Flame Brocade (_Flammea_) Red Sword-grass (_Vetusta_) Sword-grass (_Exolita_) Genus _Xylina_ Sprawler (_Sphinx_) Silver Y (_Gamma_) =Geometrae.= Feathered Thorn (_Pennaria_) Vestal (_Sacraria_) Scarce Umber (_Aurantiaria_) Mottled Umber (_Defoliaria_) Winter (_Brumata_) Northern Winter (_Boreata_) November (_Dilutata_) Juniper Carpet (_Juniperata_) Gem (_Fluviata_) Carpets (_Siderata_, _Miata_) Mallow (_Cervinata_) Streak (_Spartiata_) NOVEMBER No butterflies are to be seen this month with the exception of the hybernating species, and even these will not venture on the wing unless the weather is mild and bright for the season.
