Rearing and Description of the Early Stages of the Nearctic Species of Peridea, with Special Reference to P. Basitriens (Lepidoptera: Notodontidae)
Excerpt: The genus Peridea Stephens, according to Forbes (1948), is composed of two subgenera: Lophodonta Packard and Peridea. To the former belong the two species, angulosa (J.E. Smith, 1797) and ferruginea Packard, 1864; to the latter only one species, basitriens (Walker, 1855). The foodplant of angulosa is given by Forbes (1948) as oak, that of ferruginea as birch. The larva of basitriens has never been described, while the larvae of the other two species have been described and figured in color by Packard (1895).
Efforts to fill this gap in our knowledge have been made by several lepidopterists, but there has been no report of successful rearing of basitriens. The most recent investigator to publish a detailed report about the failure to rear basitriens was Ferguson (1963). Efforts to rear basitriens were also made at the Entomology Research Institute, Canada Department of Agriculture, Ottawa, Ont., but without success; on the report sheet is the interesting remark that the little caterpillars dried after hatching from the eggs
Zur Synonymie von Leucophlebia lineata brunnea Closs nebst Bemerkungen zu einigen Sphingiden aus Sauters Formosa-Ausbeute in der Sammlung des Deutschen Entomologischen Institutes (Lepidoptera: Sphingidae).

Drivers of site fidelity in ungulates
1. While the tendency to return to previously visited locationsâtermed âsite fidelityââis common in animals, the cause of this behaviour is not well understood. One hypothesis is that site fidelity is shaped by an animal's environment, such that animals living in landscapes with predictable resources have stronger site fidelity. Site fidelity may also be conditional on the success of animalsâ recent visits to that location, and it may become stronger with age as the animal accumulates experience in their landscape. Finally, differences between species, such as the way memory shapes site attractiveness, may interact with environmental drivers to modulate the strength of site fidelity.
2. We compared interâyear site fidelity in 669 individuals across eight ungulate species fitted with GPS collars and occupying a range of environmental conditions in North America and Africa. We used a distanceâbased index of site fidelity and tested hypothesized drivers of site fidelity using linear mixed effects models, while accounting for variation in annual range size.
3. Mule deer Odocoileus hemionus and moose Alces alces exhibited relatively strong site fidelity, while wildebeest Connochaetes taurinus and barrenâground caribou Rangifer tarandus granti had relatively weak fidelity. Site fidelity was strongest in predictable landscapes where vegetative greening occurred at regular intervals over time (i.e. high temporal contingency). Species differed in their response to spatial heterogeneity in greenness (i.e. spatial constancy). Site fidelity varied seasonally in some species, but remained constant over time in others. Elk employed a âwinâstay, loseâswitchâ strategy, in which successful resource tracking in the springtime resulted in strong site fidelity the following spring. Site fidelity did not vary with age in any species tested.
4. Our results provide support for the environmental hypothesis, particularly that regularity in vegetative phenology shapes the strength of site fidelity at the interâannual scale. Large unexplained differences in site fidelity suggest that other factors, possibly speciesâspecific differences in attraction to known sites, contribute to variation in the expression of this behaviour.
5. Understanding drivers of variation in site fidelity across groups of organisms living in different environments provides important behavioural context for predicting how animals will respond to environmental change
Supplement I to E. C. Zimmerman, âInsects of Hawaiiâ Vol. 7 (1958) Macrolepidoptera
This supplement concerns species of the family Sphingidae (pages 425-444) introduced to Hawaii since 1958 and now firmly established. The introductions are connected with the rapid growth of air traffic between Hawaii and SE Asia since the mid-1970s. Of special interest is the fast interisland colonization as reported in the HAWAII COOPERATIVE ECONOMIC INSECT REPORT (HCEIR), published by the State Department of Agriculture, Honolulu, HI until 1980, subsequently called HAWAII PEST REPORT
