These species-groups are briefly contrasted to Agrilus (s. str. fide Alexeev 1998) and the species of each group

The genera Brachys, Chalcophora, Chrysesthes, Cinyra, Hylaeogena andSpectralia are reported for first time from Nicaragua. For each species is given the geographical distribution and some biological data when available.

These species can be separated into two groups, the megacephala
Wasps robbing food from ants: a frequent behavior?

For insects, intrafamilial food robbing is known among ants, but social wasps (Vespidae; Polistinae) taking food from ants has, to the best of our knowledge, never been reported. In this paper, we present two cases involving social wasps robbing food from ants associated with myrmecophytes. (1) Polybioides tabida F. (Ropalidiini) rob pieces of prey from Tetraponera aethiops Smith (Formicidae; Pseudomyrmecinae) specifically associated with Barteria fistulosa Mast. (Passifloraceae). (2) Charterginus spp. (Epiponini) rob food bodies from myrmecophytic Cecropia (Cecropiaceae) exploited by their Azteca mutualists (Formicidae; Dolichoderinae) or by opportunistic ants (that also attack cleptobiotic wasps). We note here that wasps gather food bodies (1) when ants are not yet active; (2) when ants are active, but avoiding any contact with them by flying off when attacked; and (3) through the coordinated efforts of two to five wasps, wherein one of them prevents the ants from leaving their nest, while the other wasps freely gather the food bodies. We suggest that these interactions are more common than previously thought.

The authors first document considerable spatial variation in light and, to a lesses extent, temperature and relative humidity, and then summarize research to date on the responses of plants to environmental variation in light. Although plants at La Selva are remarkably shade tolerant, including species commonly considered pioneer or shade ...
