The Diversity of Insects Visiting Flowers of Saw Palmetto (Arecaceae)
Deyrup & Deyrup: Insect Visitors of Saw Palmetto Flowers 711 THE DIVERSITY OF INSECTS VISITING FLOWERS OF SAW PALMETTO (ARECACEAE) MARK DEYRUP1,* AND LEIF DEYRUP2 1Archbold Biological Station, 123 Main Drive, Venus, FL 33960 2Univ. of the Cumberlands, Williamsburg, KY 40769 *Corresponding author; E-mail: [email protected] ABSTRACT A survey of insect visitors on flowers ofSerenoa repens (saw palmetto) at a Florida site, the Archbold Biological Station, showed how nectar and pollen resources of a plant species can contribute to taxonomic diversity and ecological complexity. A list of 311 species of flower visitors was dominated by Hymenoptera (121 spp.), Diptera (117 spp.), and Coleoptera (52 spp.). Of 228 species whose diets are known, 158 are predators, 47 are phytophagous, and 44 are decomposers. Many species that visited S. repens flowers also visited flowers of other species at the Archbold Biological Station. The total number of known insect-flower relation- ships that include S. repens is 2,029. There is no evidence of oligolectic species that are de- pendent on saw palmetto flowers. This study further emphasizes the ecological importance and conservation value of S. repens. Key Words: pollination, flower visitor webs, pollinator diversity, floral resources, saw pal- metto, Serenoa repens RESUMEN Un estudio sobre los insectos que visitan las flores de Serenoa repens (palma enana ameri- cana o palmito de sierra) en un sitio de la Florida, la Estación Biológica Archbold, mostró cómo los recursos de néctar y polen de una especie vegetal puede contribuir a la diversidad taxonómica y complejidad ecológica.

ABSTRACT Hill, Hilary Nan. Phylogenetic Utility of Two New Nuclear Genes, Opsin and CAD, Within the Stiletto Flies (Diptera: Th
ABSTRACT Hill, Hilary Nan. Phylogenetic Utility of Two New Nuclear Genes, Opsin and CAD, within the stiletto flies (Diptera: Therevidae) (Under the direction of Brian M. Wiegmann). A need for multiple phylogenetic markers to reconstruct evolutionary relationships is increasingly apparent within both the Therevidae and insect systematics as a whole, especially markers that can accommodate the immense species diversity that arose during the Mesozoic (~65-250mya). Phylogenetic trees are often best reconstructed using datasets from distinct sources and from character sets that have been under different selective pressures. Many recent insect systematics studies use various combinations of markers from multiple genomes, morphology, and biogeography. Nuclear genes, particularly protein-encoding genes that are highly conserved and low copy-number, are increasingly attractive as phylogenetic markers, and there is a recent concerted effort to find and increase access to new nuclear genes. Chapter one of this study investigates the phylogenetic utility of opsin, a new multiple copy nuclear protein- encoding gene in the dipteran family Therevidae. The present analyses of nucleotide sequence data of opsin reconstructed a therevid phylogeny that is partially concordant with previous classifications which demonstrates that opsin may have some limited utility as a phylogenetic marker within the Therevidae and closely related Diptera, but also shows that opsin may be better used in combination with other molecular markers or morphological data sets. Phylogenetic analyses of opsin at multiple levels within insects supports these results, but also reveals the significant obstacles in technical manipulation of the gene and in the interpretaion of ortholog/paralog relationships. In the second chapter two new nuclear, protein-encoding genes, opsin and CAD, in combination with EF-1α and 28S rDNA, are applied to reconstruct evolutionary relationships among the major lineages of Therevidae for which previous molecular evidence has been insufficient. -

Wiesenborn1 ABSTRACT.—Phoradendron juniperinum (Viscaceae) is a dioecious, parasitic plant of juniper trees ( Juniperus [Cupressaceae]) that occurs from eastern California to New Mexico and into northern Mexico. The species produces minute, spherical flowers during early summer. Dioecious flowering requires pollinating insects to carry pollen from male to female plants. I investigated the pollination of P. juniperinum parasitizing Juniperus osteosperma trees in the Cerbat Mountains in western Arizona during June–July 2016. I examined pollen from male flowers, aspirated insects from female flowers, counted conspecific pollen grains on insects, and estimated floral constancy from proportions of conspecific pollen in pollen loads. -

ROBBER-FLIES and EMPIDS ROBBER-FLIES Asilidae. Very
ROBBER-FLIES and EMPIDS Asilus ROBBER-FLIES Asilidae. Very bristly predatory flies that head from front generally chase and catch other insects in mid-air. Most species sit in wait and dart out when likely prey appears. The prey is then sucked dry with the stout proboscis, which projects horizontally or obliquely forward. There is a deep groove between the eyes in both sexes, the eyes never touching even in males. A 'beard' on the face protects eyes from struggling prey. Legs are sturdy and have 2 pads at most. Wings folded flat over body at rest. Larvae eat some dead vegetable matter, but most are at least partly predatory and some feed mainly on beetle and fly grubs in the soil. Asilus with prey As Asi/us crabroniformis. An unmistakable fly - one of the largest in B - inhabiting open country 7-10. A very strong flier. Breeds in cow pats and other dung. Dasypogon diadema. First 2 long veins both reach wing margin: wing membrane ribbed. Front tibia has curved spine at tip. Male more uniformly black, with dark wings. 6-8 in scrubby places, especially coastal dunes. S. ;., Leptogaster cylindrica. Feet without pads. Hind femur yellow. 3rd antennal segment ends in bristle. One of the slimmest robber-flies, it resembles a crane-fly in flight. It hunts in grassy places, flying slowly and plucking aphids from the grasses. 5-8. A L. guttiventris is similar but has reddish hind femur. 85 Dioctria atricapi/la. First 2 long veins reach margin. Beard rather sparse and, as in all Oioctria species, the antennae spring from a prominence high on the head. -

Metatrichia dhimurru sp. nov. is described from Arnhem Land (Northern Territory), Australia and represents the third species of the genus to be described from the Australasian region. Metatrichia venezuelensis sp. nov. from Venezuela is the third extant species of the genus to be described from the New World. Key words: Metatrichia, Asiloidea, Therevoid clade, Scenopinidae Introduction Scenopinidae (window flies) are a small family (ca. 420 species in 24 genera) of asiloid flies distributed on all continents except Antarctica. This family is closely related to Therevidae (stiletto flies) based on the characteristic secondarily segmented larval abdomen. Scenopinids are typically very small insects, frequently less than 5 mm in total body length. Adults are known to feed at flowers and honey dew, while larvae are predators in sandy soils and leaf litter, although larvae of some species have been reared from wood boring beetle galleries, bird nests and small mammal burrows (Kelsey 1969). -
Introduction
PDF file from Evenhuis, N.L. & D.J. Greathead, 1999, World Catalog of Bee Flies (Diptera: Bombyliidae). Backhuys Publishers, Leiden. xlviii + ix 756 pp. INTRODUCTION Bombyliids, or bee flies as they are commonly called, comprise a diverse and speciose assemblage of brachycerous flies. With more than 4,500 species known worldwide, they are one of the largest families of Diptera, surpassed in numbers of species only by the Tipulidae (14,000), Tachinidae (9,200), Syrphidae (5,800), Asilidae (5,600), Ceratopogonidae (5,300), and Dolichopodidae (5,100). They occur in a variety of habitats and ecosystems (from ca. 10 km from the Arctic Ocean in Canada through all latitudes as far south as Tierra del Fuego; and at altitudes from over 3500 m in the Himalayas to 200 m below sea level at the shores of the Dead Sea). They are found on all continents except Antarctica and also many oceanic islands. The family has a remarkable range in size (from some Exoprosopa with wingspans of more than 60 mm to the tiny Apolysis that can be as small as 1.5 mm in length) and variety of shapes (e.g., Systropus mimicking ammophiline wasps; Bombomyia mimic- king bumblebees). The adults of the larger species are powerful and agile fliers, rivaling the syrphid flies in their ability to hover and move in all directions while in flight. With many species possessing colorful patterns of stripes and spots on the wings and bodies, bee flies are often some of the most striking in appearance of all the Diptera. Individuals can often be seen either resting in the open on trails or on rocks or twigs sunning themselves, or feeding on a variety of flowering plants. -
