Survival and reproductive challenges for male harvestmen that build and care nests

Authors: Rojas-Valle, A. & Solano, D.

Underneath massive rotting logs in the forest, “harvestmen” or opilions (which are arachnids similar to spiders and scorpions) build their nests using wood debris where they mate with females. The females deposit their eggs inside the cuplike nests and leave the males with the task of taking care of the nest and eggs. However, the maintenance of a mud nest in a habitat where heavy amounts of rainfall can last for several days is not an easy job. But from our research long-lasting nests are not a guarantee that females will mate and lay their eggs in a nest. So some of the questions we are asking of the harvestmen are: What makes some nests last longer than others? And why are some nests/males more successful with mating than others?

To answer these and other questions, we are monitoring four logs in the forest for at least one year, where we are collecting data regarding general nest conditions, male presence, juvenile and females inside the nests, fungi and external factors that may affect the nests. In a parallel study we have worked with the researcher Carlos Toscano from the Clemente Estable Biological Research Institute (IIBCE) from who specifies in the reproductive behavior of arachnids.

Harvestmen Nest

Diversity, abundance and annual activity of the Veraguas’s butterflies.

Author: Julian Solano Salazar

The Lepidoptera order is the second largest order in the world, with more than 150,000 described species, but there are an estimated of 300,000 to 500,000 spread over all the earth (Chacon & Montero, 2007). Neotropical Region includes the highest percentage of butterfly species described worldwide, reaching an estimated 42% of the species of the families Papilionidae and Hesperidae (Lamas 2000). In Costa Rica the Lepidoptera order is present with about 13,000 species, of which about 1600 are diurnal butterflies.

This research aims to study the diversity, abundance of butterflies and the annual activity of the species in association with the kind of ecosystem and also describe the immature stages of some especies. To achieve these objectives, we have 3 systematic monitoring per month using; free collect (entomological net), light trap and fuit traps in the canopy and in the underwood.

According to the results of the latest report we have identified over 549 species distributed in 21 families. The most diverse is the family Nymphalidae with 177 species, followed by the Arctiidae family with 96 species. This list includes three species reported for the first time in Costa Rica, Memphis nenia, Adelpha Attica Attica and Dynastor macrosiris strix, all belonging to the family Nymphalidae. Tetrisia florigera species (Noctuidae), which was missing for 98 years in Costa Rica are also rediscovered In Veragua. These results will be published in scientific journals, but also will be used to establish conservation strategies in the area, as well as environmental education programs in the community and nationally.

Abstract

Touroultia, a new genus of Onciderini Thomson, 1860 (Coleoptera: Cerambycidae: Lamiinae) is described and illustrated. Five new species of Onciderini are also described and illustrated: Jamesia ramirezi from Costa Rica; Peritrox marcelae from French Guiana; Touroultia swifti from Ecuador; Touroultia lordi from French Guiana; Trestoncideres santossilvai from Brazil. Keys to the known species of Peritrox Bates, 1865; Touroultia gen. nov.; and Trestoncideres Martins and Galileo, 1990 are provided. The following new synonymies are proposed: Calliphenges Waterhouse, 1880 (Colobotheini) = Malthonea Thomson, 1864 (Desmiphorini); Paraclytemnestra Breuning, 1974 (Onciderini) = Jamesia Jekel, 1861 (Onciderini); Orteguaza Lane, 1958 (Apomecynini) = Clavidesmus Dillon and Dillon, 1946 (Onciderini). The following new combinations are proposed: Clavidesmus funerarius (Lane, 1958) (Onciderini); Clavidesmus lichenigerus (Lane, 1958) (Onciderini); Ischiocentra insulata (Rodrigues and Mermudes, 2011); Malthonea cuprascens (Waterhouse, 1880) (Desmiphorini); Touroultia obscurella (Bates, 1865) (Onciderini). The following species is restored to original combination: Jamesia lineata Fisher, 1926 (Onciderini). The following 13 new country records are reported: Ataxia hovorei Lingafelter and Nearns, 2007 (Pteropliini) (Haiti); Carterica soror Belon, 1896 (Colobotheini) (Ecuador); Colobothea lunulata Lucas, 1859 (Colobotheini) (Colombia); Curius punctatus (Fisher, 1932) (Curiini) (Haiti); Cyclopeplus lacordairei Thomson, 1868 (Anisocerini) (Colombia); Iarucanga mimica (Bates, 1866) (Hemilophini) (Ecuador); Pirangoclytus latithorax (Martins and Galileo, 2008) (Clytini) (Costa Rica); Porangonycha princeps (Bates, 1872) (Hemilophini) (Colombia); Trestonia lateapicata Martins and Galileo, 2010 (Onciderini) (Brazil); Tulcus dimidiatus (Bates, 1865) (Onciderini (Colombia); Unaporanga cincta Martins and Galileo, 2007 (Hemilophini) (Colombia); Zeale dubia Galileo and Martins, 1997 (Hemilophini) (Colombia); Zonotylus interruptus (Olivier, 1790) (Trachyderini) (Colombia).
