Eulaema bombiformis, E. meriana, and Mullerian Mimicry in Related Species (Hymenoptera: Apidea)
Biotropica, 1979 Eulaema bombiformis, E. meriana, and E. seabrai form part of a Miillerian mimetic complex in the Amazon basin, and all three are exceedingly similar in that region. In eastern coastal Brazil all three species are found, but they are not mimetic there, and are easily distinguished. In coastal Venezuela and northern Central America, E.

Neotropical Entomology, 2023
Mountain ecosystems experience abrupt abiotic changes that represent environmental filters for many organisms, shaping their phenotypic expressions. However, little is known about the morphological and symmetric adjustments of native bees along altitudinal gradients. We evaluated the changes on wing morphology, wing size, and vein fluctuating asymmetry

Zoologischer Anzeiger, 2021
Abstract Environmental changes alter the selective pressures acting on species, leading to different responses. Morphological variation can increase a species’ ability to occupy different habitats, persist in uncertain environments and stabilize its interactions with other species. We examined the morphological variation (wings, thorax and tibiae) of

Conopid Fly (Diptera: Conopidae) Attacking Large Orchid Bees (Hymenoptera: Apidae: Eulaema)
Journal of the Kansas Entomological Society, 2004Conopidae is a large and widespread family of parasitic flies. The conopid genus Physocephala is often associated with the social bumble bees (Hymenoptera: Apidae: Bombus). Smith (1966) lists 13 named Physocephala species and their hosts, of which 11 were known to attack Bombus in the Nearctic and Palaearctic regions.

Scent-robbing and fighting among male orchid bees, Eulaema (Apeulaema) nigrita Lepeletier, 1841 (Hymenoptera: Apidae: Euglossini) [PDF]
Biota Neotropica, 2010 Male Neotropical orchid bees (Euglossini) collect volatile chemicals from floral and non-floral sources and store then in specialized hind tibial structures. The ultimate causes of euglossine fragrance collection remain a mystery.
