  • Adaptations of Insects at Cloudbridge Nature Reserve, Costa Rica
    Adaptations of Insects at Cloudbridge Nature Reserve, Costa Rica Aiden Vey Cloudbridge Nature Reserve July 2007 Introduction Costa Rica’s location between North and South America, its neotropical climate and variety of elevations and habitats makes it one of the biodiversity hotspots of the world. Despite being only 51,100km² in size, it contains about 5% (505,000) of the world’s species. Of these, 35,000 insect species have been recorded and estimates stand at around 300,000. The more well known insects include the 8,000 species of moth and 1,250 butterflies - almost 10% of the world total, and 500 more than in the USA! Other abundant insects of Costa Rica include ants, beetles, wasps and bees, grasshoppers and katydids. The following article presents a select few aspects of the insect life found at Cloudbridge, a nature reserve in the Talamanca mountain range. Relationships Insects play many important roles in Costa Rica, including pollination of the bountiful flora and as a food supply for many other organisms. The adult Owl butterfly (Caligo atreus, shown at right) feeds on many Heliconiaceae and Musaceae (banana) species, in particular on the rotting fruit. They are pollinators of these plants, but also use the leaves to lay eggs on. When hatched, the larvae remain on the plant and eat the leaves. Being highly gregarious, they can cause significant damage, and are considered as pests (especially in banana plantations). However, there are a number of insects that parasitise the Caligo larvae, including the common Winthemia fly (left) and Trichogramma and Ichneumon wasps, which act as biological control agents.

(Orthoptera, Tettigonioidea, Phaneropteridae): second contribution to neotropical Phaneropterinae.— The new tribe Pycnopalpini is proposed, based on morphological similarity among the genera Hetaira, Pycnopalpa, Topana (Pycnopalpina n. subtr.), Dolichocercus, Oxyprorella, Theia, and Theiella n. gen. (Theiina n. subtr.). We include a key to separate subtribes and genera. We also described the male of Theia unicolor, Theia bifurcata n. sp., Theiella amazonica n. sp., Theiella andina n. sp., and D. santanderensis n. sp. from Colombia, and D. costaricensis n. sp. from Costa Rica. Hetaira (Atopana) morona and Hetaira (Atopana) varia are recorded from the Colombian Amazon, where both species seem to occur sympatrically. Theia peruviana n. comb. is also recorded from the Colombian Amazon, where it seems to occur sympatrically with T. bifurcata. The paper contains additional new combinations, and Oxyprorella gregoirea syn. n. is a new synonym for Insara bolivari. This contribution reconsiders the neotropical subfamily Phaneropterinae, aiming to establish the limits of the tribes and genera of this subfamily.

The first genus is divided into two subgenera (Parascudderia s. str. and Negativeria subgen. nov.) on the base of differences in the colouration of hind wings and hind tibiae as well as in the shape of last abdominal tergite in male; Parascudderia s. str. contains P. dohrni Brunner- Wattenwyl, 1891 from Brazil, P. setrina Grant, 1960 from Ecuador, P. strigilis Grant, 1960 from Brazil, and P. positiva sp. nov. from Ecuador; Negativeria subgen. nov. includes P. secula Grant, 1960 from Peru, P. astylata sp. nov. from Peru, and P. negativa sp. nov. from Ecuador. Four smaller new taxa are additionally described from South America: P. secula santacruzi subsp. nov. from Bolivia; C. pichincha sp. nov. from Ecuador; Ch. poeciloptera sp. nov. from Peru; D. cristulata sp. nov. from Ecuador. These new taxa are distinguished from all the previously described species and subspecies of the same genera by the characters of general appearance as well as some features of the copulatory ap- paratus or pronotal tubercles. New data on some other species of these subfamilies are also given.

  • Katydids Katydids Are a Large Group of Insects in the Order Orthoptera, Related to the Grasshoppers and Crickets
    A Horticulture Information article from the Wisconsin Master Gardener website, posted 25 Sept 2017 Katydids Katydids are a large group of insects in the order Orthoptera, related to the grasshoppers and crickets. Some katydids have been called long-horned grasshoppers because of their long and slender shape, but actually katydids are more closely related to crickets than to any type of grasshopper. There are about 6,400 species worldwide, with the greatest diversity in the tropics. Their classifi cation is not well established, with taxonomists differing in their classifi cation schemes. Most North American species are placed in the family Tettigoniidae and divided among seven to ten subfamilies. The main groups of commonly encountered katydids include the true katydids (Pseudophyllinae), false The greater angle-wing (Microcentrum katydids (Phaneropterinae), shield-backed katydids (Tettigoniinae rhombifolium) is a leaf mimic katydid. – but sometimes divided into three subfamilies), meadow katydids (Conocephalinae) and coneheaded katydids (Copiphorinae, but sometimes these are included with the meadow katydids). There are about 255 species in North American and 20 species in the Midwest. Tropical katydids in Costa Rica (L and LC, lichen katydid, Markia hysterix, in Costa Rica (C), and katydids in Peruvian Amazon (RC and R). Katydids are usually green and camoufl aged to blend in with foliage, more commonly heard than seen. They have a body taller than it is wide and thin and hind legs that are longer than the other pairs of legs. Some characteristics that distinguish katydids from other orthopterans include having the wings held vertically over body (like a roof of a house), hearing organs on the front tibia, all tarsi with 4 segments (crickets have 3), a typically fl attened and sword-like ovipositor, and very long, thin antennae as long as Black-legged meadow katydid or longer (Orchelimum nigripes).
