AbstractA method is described for sampling aquatic insects using black light. Trap design, description of its placement, and conversion to a fumigator is explained. Total numbers of emerging insects captured by aquatic light trap are given and compared with catches in surface and bottom cone traps. Overall effectiveness of the black light trap is discussed.

Extensive Damage

Most of the approximately 75 known eggs of the extinct great auk ( Pinguinus impennis) are in public museums, with a few in private collections. A small number of these eggs has sustained damage, either at the time of collection or subsequently, and two of these eggs are known to have been repaired. The two eggs suffered rather different types of damage and were subsequently restored using different techniques. The first, known as Bourman Labrey's egg, sustained extensive damage sometime prior to the 1840s, when the shell was broken into numerous pieces. This egg was repaired by William Yarrell in the 1840s, and when it was restored again in 2018, it was discovered that Yarrell's restoration had involved the use of an elaborate cardboard armature. This egg is currently in a private collection. The second egg, known as the Scarborough egg, bequeathed to the Scarborough Museum in 1877, was damaged (by unknown causes) and repaired, probably by the then curator at Scarborough, W. J. Clarke, in 1906. This egg was damaged when one or more pieces were broken adjacent to the blowhole at the narrow end (where there was some pre-existing damage). The media reports at the time exaggerated the extent of the damage, suggesting that the egg was broken almost in two. Possible reasons for this exaggeration are discussed. Recent examination using a black light and ultraviolet (UV) revealed that the eggshell had once borne the words, “a Penguin's Egg”, that were subsequently removed by scraping.

Opportunistic Feeding

By using a 'black light' and playback of sounds made by foraging insectivorous bats, we examined opportunistic feeding behavior of bats near Camp Verde, Arizona, between 1 and 10 June 1975. Bats were significantly most active during 15-min periods when the light was on and insects were aggregated over it. Bats feeding over the light selectively pursued and captured larger insects, apparently ignoring the smaller ones. Bats did not respond to sounds simulating feeding buzzes of bats, but showed a slight response to the foraging sounds of other bats. Opportunistic feeding by insectivorous bats allows effective exploitation of patchily distributed food resources and can lead to selective feeding when 'hatches' of insects are involved. Opportunistic feeding is not incompatible with selective feeding, and may eventually be established as a strategy common to most insectivorous bats.

INTRODUCTION: Triatomine bug captures in the wild are laborious and time-consuming. Some traps may assist in this task. We report a new trap design and the capture of a specimen of a triatomine rarely found. METHODS: Two luminous traps were installed in the city of Diamantina, State of Minas Gerais, and surveyed weekly for a year. RESULTS: A Triatoma arthurneivai female and other triatomine bugs were caught. CONCLUSIONS: A new trap design may be used in triatomine bugs field captures, mainly in low density areas. We assume the center of endemism of Triatoma arthurneivai is the Espinhaço Mountain range.

Ombrophilous Forest

The richness and abundance of the assemblage of species in a community are a way to understand the patterns of diversity found around the world. This study describes the assemblages of Saturniidae and Sphingidae in an area of Montana Mixed Ombrophilous Forest, Tijucas do Sul, Paraná, Brazil, 880m, 25º50'8.93"S, 49º 02'55.20"W. Samples were collected between November 2010 and September 2011 during two nights at the twelve new moons periods with a light trap equipped with black light lamp (ultraviolet) of 46 watts between two mercury mixed-light lamps HWL 250 watts from 6:00 p.m to 06:00 a.m. The sampling effort totaled 288 hours. This sampling effort was responsible for the capture of 1235 specimens, distributed in 124 species: 858 specimens and 86 species of Saturniidae, and 377 specimens and 38 species of Sphingidae. It is noteworthy the sampling of 10 new species: one of Automerella Michener, 1949, two of Hylesia Hübner, [1820], one of Lonomia Walker, 1855 and six of Periga Walker, 1855, that will be described.

Effective Design

Eight different pit-trap designs were compared to determine the most effective design for capturing reptiles in arid spinifex grasslands of central Australia. Results from seven surveys within two studies showed that more complicated designs with cross fences did not significantly increase trapping success. A simple straight line of pit-traps and drift fence with buckets approximately 7 m apart is the most effective design and is recommended for sampling reptiles in arid Australia.
