The African Euthyplociidae (Ephemeroptera) (Exeuthyplo~Iinae Subfam
Aquatic Insects, Vol. 2 (1980), Number4, pp. 217-224. The African Euthyplociidae (Ephemeroptera) (Exeuthyplo~iinae subfam. n.) by M. T. GILLIES ABSTRACT A description is given of the larva of Exeuthyplocia Lestage, which closely resembles that of Afroplocia Lestage. On the basis of larval and adult characters and the apparent burrowing habits of the larvae, a new subfamily, Exeuthyplociinae, is proposed for the two African genera of Euthyplociidae. The Euthyplociidae are a mainly tropical and subtropical family, represented in Africa by the two monotypic genera, Exeuthyplocia Lestage and Afroplocia Lestage. Lestage (1921), in recognising the subfamily Euthyplociinae, never theless placed Exeuthyplocia in the Polymitarcinae on the grounds of greater affinity with the latter group than the former. Demoulin (1952), in a comprehensive review, transferred Exeuthyplocia to the Euthyplociinae, treating this as a subfamily of the Ephoronidae. Dealing with the adults only, he characterised the Euthyplociinae as having the fore wing with small inter calaries or with marginal anastomoses, MA forking distal to or at the same level as RS and the cubital field with numerous sigmoidal veinlets. Edmunds and Traver (1954) endorsed this action by elevating the group to family level. The larvae of the Euthyplociidae have generally been regarded as sprawling forms, related to but separate from the true, burrowing forms such as the Ephemeridae and Polymitarcidae (Edmunds, Allen and Peters, 1963; De moulin, 1970; Edmunds, Jensen and Berner, 1976). However, while this is true for most members of the family of which the larvae are known, it overlooks the fact that in Afroplocia the fore tibia is flattened to an extent that suggests fossorial habits (Barnard, 1940; Edmunds, 1972). -
Yellow Mayfly (Potamanthus Luteus )
SPECIES MANAGEMENT SHEET Yellow mayfly (Potamanthus luteus ) The Yellow mayfly is one of Britain’s rarest mayflies. The nymphs or larvae of this mayfly typically live in silt trapped amongst stones on the riverbed in pools and margins and grow to between 15 and 17mm. They are streamlined with seven pairs of thick feathery gills that are held outwards from their sides. The adults have three tails and large hindwings. The body is a dull yellowish-orange with a distinctive broad yellowish brown stripe along the back. The wings are yellow and the cross-veins are a dark reddish colour. Due to its rarity and decline in numbers this insect has been made a Priority Species on the UK Biodiversity Action Plan (BAP). Life cycle There is one generation of this mayfly a year which overwinters as larvae. The adult mayflies are short lived and emerge between May and late October (with peak emergence in July). They will typically emerge at dusk and usually from the surface of the water, although they may also emerge by climbing up stones or plant stems partially or entirely out of water. Distribution map This mayfly is historically a rare species with populations in the River Wye and Usk, Herefordshire. The most recent surveys show a dramatic decline in the River Wye population and have failed to find this species in the River Usk. A small population has however recently been found in the River Teme in Worcestershire. Habitat In the Herefordshire streams where this species has been found, the larvae have been found under loose stones, preferring mobile sections of shingle or a mixture of larger stones with loose shingle such as those found downstream of bridges or at the confluence of tributaries. -

Feeding habits, fine structure and microhabitat preference of Euthyplocia hecuba (Hagen, 1861) (Ephemeroptera: Euthyplociidae) nymphs from Honduras. Folia biol. (Kraków) 56: 43-49. The Euthyplociidae are a tropical and subtropical Ephemeropteran group. The aim of this study was to augment knowledge on some aspects of the biology and ecology of Euthyplocia hecuba (Hagen, 1861) nymphs. Mayflies were collected in the Rio El Padre, located on the Caribbean slope of Honduras. Diet, microhabitat preference and some fine morphological aspects of the nymphs were examined. E. hecuba nymphs are very specialised organisms that occupy a specific ecological niche in the lotic/benthic community. Immature stages show an evident preference for life in soft and fine substrata. They are detritivorous burrowers that ingest large amounts of fine particles deposited by river flow in sedimentation areas. They show peculiar morphological adaptations for life in this particular substratum, such as mouthparts modified for digging and collection of fine organic sediments, digging legs with shovel-like tibiae and massive femora, and filamentous gills.

Ephemeroptera) with Key to Their Identification
Rec. %001. Surv. India, 88 ( 1 ): 135 -145, 1991 ON AN ACCOUNT OF INDIAN HEPTAGENllDAE (EPHEMEROPTERA) WITH KEY TO THEIR IDENTIFICATION v. D. SRIVASTAVA Zoological Survey ofIndia, New A lipo re , Calcutta - 700053. INTRODUCTION Mayflies are amphibiotic insect and represent order Ephemeroptera, which inhabit both lotie and len tic ecosystem of our water. Heptageniidae is one of the family of these insects, which in our country is represented by 13 species under 7 genera. It represents almost one seventh of the whole component of Indian mayflies, others are represented by 77 species under 24 genera and 11 families. This is the third biggest, family among Indian Ephemeroptera. World over this family is represented by 378 species under 28 genera (Table - 1, page 144). All the species of this family are endemic to India, though one has extended distribution in orient, thus we have essentially and exclusively oriental element represented under this family. Heptageniidae has 7 species represented in the zone of higher elevation ranging between 1900 to 5297 meters above mean sea level. Ororotsia hutchinsoni Traver (1939) has been recorded as larvae in a lentic fresh water lake at an altitude of 5297 m which happens to be highest elevation record for any mayfly within our limits. Ofour 13 Heptageniidse, male of9, female of 12 and larvae ofonly 1 is known (Table - II, page 145), A key has been formulated to distinguish all 7 genera and 13 species of Indian Heptageniids. SYSTEMATIC Heptageniidae is one of the most distinctive family of mayflies represented almost ·all over the world by 378 species under 28 genera. -

Inside: Aquatic Insects Constructing Caddisflies Toothed Dragon Marvelous Mayflies Nature's Red Flags Be Outside - Fishing is Fun idfg.idaho.gov Aquatic Insects Aquatic insects have some things in common with all insects. They have six legs. They have no bones but are covered by an exoskeleton, a shell similar to your fingernails. They also have three main parts to their body: head, thorax and abdomen. To be called aquatic insects, insects must spend part of their lives in water. They may live beneath the water surface or skim along the top. Some examples of aquatic insects are mosquitoes, dragonflies and caddisflies. Aquatic insects come in many shapes and sizes, and they all have some interesting ways of dealing with living in and on water. If you were an insect living underwater, how would you breathe? Insects are animals, so they need oxygen to survive. Many aquatic insects have gills, just like fish. The gills may be attached to the outside of the insect’s body or found inside the body. Some insects have tubes sticking out of their abdomens. They stick the tube above the water and breathe the same air you breathe. They may even stick the tube into plants underwater. They get oxygen straight from the plants that make it! Other aquatic insects, like diving beetles, grab bubbles of air and pull them underwater. The beetles carry the bubble in their back legs as they swim. Once they have used all the air in the bubble, they go up and grab another bubble. -

Out of these, six orders contain species engaged in entomophagy, but very few are being harvested effectively, leading to over-exploitation and local extinction. Examples of existing practices are given, ranging from the extremes of including insects (e.g., dipterans) in the dietary cores of many indigenous peoples to consumption of selected insects, by a wealthy few, as novelty food (e.g., caddisflies). The comparative nutritional worth of aquatic insects to the human diet and to domestic animal feed is examined. Questions are raised as to whether natural populations of aquatic insects can yield sufficient biomass to be of practicable and sustained use, whether some species can be brought into high-yield cultivation, and what are the requirements and limitations involved in achieving this? Keywords: aquatic insects; entomophagy; human diet; animal feed; life histories; environmental requirements 1. Introduction Entomophagy (from the Greek ‘entoma’, meaning ‘insects’ and ‘phagein’, meaning ‘to eat’) is a trait that we Homo sapiens have inherited from our early hominid ancestors. -

Arthropods, as the most species-rich and morphologically disparate animal phylum, have received substantial attention, particularly with regard to questions such as the timing of habitat shifts (e.g. terrestrialisation), genome evolution (e.g. gene family duplication and functional evolution), origins of novel characters and behaviours (e.g. wings and flight, venom, silk), biogeography, rate of diversification (e.g. Cambrian explosion, insect coevolution with angiosperms, evolution of crab body plans), and the evolution of arthropod microbiomes. We present herein a series of rigorously vetted calibration fossils for arthropod evolutionary history, taking into account recently published guidelines for best practice in fossil calibration. -
