Abstract Using a mobile crane system covering a canopy area of about 1.4 ha in a rain forest in southern Venezuela, adults of several species of Agra Fabricius were observed and captured. Adults of 17 species were kept in the laboratory. Movements and foraging behaviour in the forest canopy and in the laboratory are reported. Larvae of four Agra species are described. Larvae of all four species are highly modified. Short antennae, multiple setae FR8/9, elongate head capsule with enlarged…

Abstract Two species occurring in southeastern Texas, USA, of the predominately tropical genus Agra Fabricius, 1801 are described as new: oblongopunctata group - Agra rileyi Erwin, new species

Polyphagy and florivory prevail in a leaf-beetle community (Coleoptera: Chrysomelidae) inhabiting the canopy of a tropical lowland rainforest in southern Venezuela

TLDR
Most canopy chrysomelid beetle fauna observed and collected at canopy trees for 1 year revealed broader plasticity in host tissue selection, and insights into beetle seasonality, diurnal/nocturnal activity and intra-canopy migration are provided.

Agra, arboreal beetles of Neotropical forests: pusilla group and piranha group systematics and notes on their ways of life (Coleoptera, Carabidae, Lebiini, Agrina)

TLDR
Revisions of two new species groups of the genus Agra Fabricius are presented, with species of adults that are the smallest in the entire genus, although this does not indicate they are closely related based on other attributes.

Composition and Host-Use Patterns of a Scarab Beetle (Coleoptera: Scarabaeidae) Community Inhabiting the Canopy of a Lowland Tropical Rainforest in Southern Venezuela

TLDR
With this study, it could be shown how species of Scarabaeidae track available food resources within the canopy of a tropical rainforest.

The Beetle Family Carabidae of Costa Rica: Twenty-nine new species of Agra Fabricius 1801 (Coleoptera: Carabidae, Lebiini, Agrina)

TLDR
Based on a study of 1,100 specimens of the genus Agra from Costa Rica, twenty-nine new species were discovered and are here validated and described: A. delgadoi, n.

Extrafloral nectaries mediate the arboreal beetle community (Coleoptera) in a Neotropical rainforest

TLDR
It is demonstrated unequivocally that EF nectar is a frequently utilised food resource of many beetle adults and beetles have been a significantly underestimated visitor group, supporting the hypothesis that EFNs influence the occurrence and structure of beetle communities.

Flowers are essential to maintain high beetle diversity (Coleoptera) in a Neotropical rainforest canopy

TLDR
It is suggested that the enormous diversity of canopy beetles in Amazonian tropical rainforests is due mainly to flowers and that mass-flowering trees with small white flowers of the generalist syndrome play a particularly crucial role in assembly and nourishment of this megadiverse beetle community.

Life Cycle and Predation Potential of the Neotropical Ground Beetle Selenophorus seriatoporus Putzeys (Coleoptera: Carabidae) on Different Substrates

TLDR
Third instars and adults of S. seriatoporus demonstrated high predation potential, showing their suitability as biological control agents, and this carabid showed faster development, lower mortality, and greater longevity on soil.

What shapes ground beetle assemblages in a tree species-rich subtropical forest?

TLDR
Ground beetles seem to respond differently to environmental variables than ants and spiders, two other predominantly predatory arthropod groups that were studied on the same plots in the study area and which showed distinct relationships with woody plant richness.

A Comparison of the Beetle (Coleoptera) Fauna Captured at Two Heights Above the Ground in a North American Temperate Deciduous Forest

ABSTRACT We compared the beetle fauna captured in 12 pairs of flight intercept traps suspended at two different heights above the ground (≥15 m and 0.5 m) in a temperate deciduous forest in the

Arboreal beetles of Neotropical forests : Agra Fabricius, the Novaurora complex: Coleoptera:Carabidae:Lebiini:Calleidina

TLDR
The neotropical carabid genus Agra, whose range extends from southern Texas to northern Argentina contains more than 2 000 species, making it the largest monophyletic lineage at the generic level known of predatory beetles.

SYSTEMATIC, NATURAL HISTORY, AND ZOOGEOGRAPHIC NOTES ON THE GENUS AGRA FABRICIUS, WITH A DESCRIPTION OF A NEW SPECIES FROM PANAMA (COLEOPTERA:CARABIDAE:LEBIINI)

TLDR
The purposes of this paper are to set forth objectives of the long term Agra study, provide some information for collectors, encourage loan of material, and make known a new species from Panama in need of a name for another publication.

Agra, arboreal beetles of Neotropical forests: platyscelis‐grovip systematics (Carabidae)

TLDR
This paper is the second in a series designed to cover taxonomi‐cally all species‐groups of Agra, whose cumulative ranges extend from southernmost Texas to northernmost Argentina, and new methods of description are used to cover the several hundred species in less time and space.

Thoughts on the Evolutionary History of Ground Beetles: Hypotheses Generated from Comparative Faunal Analyses of Lowland Forest Sites in Temperate and Tropical Regions

TLDR
After seven years of tropical investigations, it is found that the answer to the apparent rarity of these beetles in the tropics is due to patchy microdistribution, not lack of species or individuals.

Water budget of the Surumoni Crane site (Venezuela)

Since 1997, the authors have examined the main components of the water budget within a primary Amazonian rain forest in southern Venezuela at the Surumoni Crane Project site. Annual intercep- tion

Notation of primary setae and pores on larvae of Carabidae (Coleoptera: Adephaga)

Based on a study of more than 75 species of Carabidae and six species of other coleopterous families, the ancestral system of primary setae and pores on carabid larvae is established, described, and
