NUMBER 2 244 MAY I9, I 966 The Larvae of the Anthophoridae (Hymenoptera, Apoidea) Part 2. The Nomadinae BY JEROME G. ROZEN, JR.1 The present paper is the second of a series that treats the phylogeny and taxonomy of the larvae belonging to the bee family Anthophoridae. The first (Rozen, 1965a) dealt with the pollen-collecting tribes Eucerini and Centridini of the Anthophorinae. The present study encompasses the following tribes, all of which consist solely of cuckoo bees: Protepeolini, Epeolini, Nomadini, Ammobatini, Holcopasitini, Biastini, and Neolarrini. For reasons presented below, these tribes are believed to represent a monophyletic group, and consequently all are placed in the Nomadinae. It seems likely that the cleptoparasitic tribes Caenoprosopini, Ammoba- toidini, Townsendiellini, Epeoloidini, and Osirini are also members of the subfamily, although their larvae have not as yet been collected. Although the interrelationships of the numerous taxa within the Nomadinae need to be re-evaluated, the tribal concepts used by Michener (1944) are employed here. Adjustments in the classifications will certainly have to be made in the future, however, for Michener (1954) has already indicated, for example, that characters of the adults in the Osirini, the Epeolini, and the Nomadini intergrade. The affinities of the Nomadinae with the other subfamilies of the Antho- phoridae will be discussed in the last paper of the series.

  • Southwestern Rare and Endangered Plants
    Preliminary Report on the Reproductive Biology of the Threatened Chisos Mountain Hedgehog Cactus BONNIE B. AMOS and CHRISTOS VASSILIOU Angelo State University, Texas Abstract: The Chisos Mountain hedgehog cactus (Echinocereus chisoensis, Cactaceae) is a narrow endemic restricted to an approximately 100 square mile area in Big Bend National Park, Texas. It was listed as threatened in 1987 as Echinocereus chisoensis var. chisoensis. An investigation of the reproductive biology and pollination ecology conducted in 1999 and 2000 revealed the taxon to be homogamous, self-incompatible, xenogamous, and heavily dependent upon the cactus oligolectic bee, Diadasia rinconis (Anthophoridae) for pollination. Despite infrequent bee visitation, fruit set from open pollination is high and fruits produce large numbers of seeds. Predation in 2002, probably from rodents as a result of severe drought conditions, was severe on plants, flower buds, and fruits. The Chisos Mountain hedgehog cactus, or Chisos jillo (Opuntia leptocaulis DC.), ocotillo (Fouquieria pitaya (Echinocereus chisoensis W. Marshall), is 1 of splendens K.

Towards simultaneous analysis of molecular and morphological data in Hymenoptera. Ð Zoologica Scripta 28, 251±260. Principles and methods of simultaneous analysis in cladistics are reviewed, and the first, preliminary, analysis of combined molecular and morphological data on higher level relationships in Hymenoptera is presented to exemplify these principles. The morphological data from Ronquist et al. (in press) matrix, derived from the character diagnoses of the phylogenetic tree of Rasnitsyn (1988), are combined with new molecular data for representatives of 10 superfamilies of Hymenoptera by means of optimization alignment. The resulting cladogram supports Apocrita and Aculeata as groups, and the superfamly Chrysidoidea, but not Chalcidoidea, Evanioidea, Vespoidea and Apoidea. James M.

  • Wisconsin Bee Identification Guide
    WisconsinWisconsin BeeBee IdentificationIdentification GuideGuide Developed by Patrick Liesch, Christy Stewart, and Christine Wen Honey Bee (Apis mellifera) The honey bee is perhaps our best-known pollinator. Honey bees are not native to North America and were brought over with early settlers. Honey bees are mid-sized bees (~ ½ inch long) and have brownish bodies with bands of pale hairs on the abdomen. Honey bees are unique with their social behavior, living together year-round as a colony consisting of thousands of individuals. Honey bees forage on a wide variety of plants and their colonies can be useful in agricultural settings for their pollination services. Honey bees are our only bee that produces honey, which they use as a food source for the colony during the winter months. In many cases, the honey bees you encounter may be from a local beekeeper’s hive. Occasionally, wild honey bee colonies can become established in cavities in hollow trees and similar settings. Photo by Christy Stewart Bumble bees (Bombus sp.) Bumble bees are some of our most recognizable bees. They are amongst our largest bees and can be close to 1 inch long, although many species are between ½ inch and ¾ inch long. There are ~20 species of bumble bees in Wisconsin and most have a robust, fuzzy appearance. Bumble bees tend to be very hairy and have black bodies with patches of yellow or orange depending on the species. Bumble bees are a type of social bee Bombus rufocinctus and live in small colonies consisting of dozens to a few hundred workers. Photo by Christy Stewart Their nests tend to be constructed in preexisting underground cavities, such as former chipmunk or rabbit burrows.

ABSTRACT Cleptoparasite bees lay their eggs inside nests constructed by other bee species and the larvae feed on pollen provided by the host, in this case, solitary bees. The cleptoparasite (adult and larvae) show many morphological and behavior adaptations to this life style. In this paper I present some data on the cleptoparasite bees whose hosts are bees specialized to collect floral oil. Key words: solitary bee, interspecific interaction, parasitic strategies, hospicidal larvae. RESUMEN Las abejas Cleptoparásitas depositan sus huevos en nidos construídos por otras especies de abejas y las larvas se alimentan del polen que proveen las hospederas, en este caso, abejas solitarias.

Neff Central Texas Melittological Institute, 7307 Running Rope, Austin, Texas 78731, USA Received 13 June 2007 – Revised 28 September 2007 – Accepted 1 October 2007 Abstract – The components of nest provisioning behavior (resources per cell, transport capacity, trip dura- tion, trips per cell) are examined for a data set derived from the literature and various unpublished studies. While there is a trade-off between transport capacity and trips required per cell, the highest provisioning rates are achieved by bees carrying very large pollen loads at intermediate trip durations. Most solitary bees appear to be either egg or resource limited, so sustained provisioning rates over one cell per day are unusual. Provisioning rate / body size / transport capacity / solitary bees / trip duration 1.
