Spotted Snake Millipede Spotted Snake Millipede . Phylum: Arthropoda Subphylum: Atelocerata Class: Diplopoda Order: Julida Family: Blaniulidae Scientific name: Blaniulus guttulatus (Bosc, 1792) The snake like slender body and brownish or pinkish spots on the lateral sides give the name spotted snake millipede (SSM) for these creatures. SSM are soil inhabitants that feed on decaying plant material. When disturbed, they curl into a coil. Biology: They are about 15 mm long and have approximately 60 body segments. Eggs are laid in the soil. Juveniles have three pairs of legs. Number of body segments increases with each molt and it takes about a year to reach adult stage. Damage: Although they primarily feed on decomposing organic matter, they can become serious pests of cultivated crops in certain conditions. They are capable of causing both primary and secondary damage. During prolonged dry conditions SSM can be attracted to the crop plants for their moisture needs. Damage to the plant tissue due to other pests and diseases can also attract SSM. Infestation is severe in soils rich in organic matter. Rainfall can also activate their infestation. Strawberries, potatoes, sugar beets, turnips, beans, squash and other vegetables are susceptible to SSM infestation. Feeding damage to the root system can cause rapid death of the plant. Control: Proper disposal of crop residue, avoiding fields with decaying plant material, removal of old mulch or decomposing leaves can minimize the chances of infestation. Proper water management will also reduce the attractiveness of soil for SSM infestation. Reports indicate mixed results with various chemicals, but certain thiocarbamate, carbamate, organophosphate, neonicotinoid, and pyrethroid chemicals were found effective. Entomopathogenic nematodes like Steinernema feltiae are also effective in managing SSM.

  • Millipedes (Diplopoda) from Caves of Portugal
    A.S.P.S. Reboleira and H. Enghoff – Millipedes (Diplopoda) from caves of Portugal. Journal of Cave and Karst Studies, v. 76, no. 1, p. 20–25. DOI: 10.4311/2013LSC0113 MILLIPEDES (DIPLOPODA) FROM CAVES OF PORTUGAL ANA SOFIA P.S. REBOLEIRA1 AND HENRIK ENGHOFF2 Abstract: Millipedes play an important role in the decomposition of organic matter in the subterranean environment. Despite the existence of several cave-adapted species of millipedes in adjacent geographic areas, their study has been largely ignored in Portugal. Over the last decade, intense fieldwork in caves of the mainland and the island of Madeira has provided new data about the distribution and diversity of millipedes. A review of millipedes from caves of Portugal is presented, listing fourteen species belonging to eight families, among which six species are considered troglobionts. The distribution of millipedes in caves of Portugal is discussed and compared with the troglobiont biodiversity in the overall Iberian Peninsula and the Macaronesian archipelagos.

The system, developed in massive Mesozoic limestone, has two distinct resur- gences. Despite relatively limited sampling, its subterranean fauna is rich, composed of a number of local endemics, terrestrial as well as aquatic, including two remarkable relictual species, Arbasus cae- cus (Simon, 1911) and Tritomurus falcifer Cassagnau, 1958. With 38 stygobiotic and troglobiotic species recorded so far, the Coume Ouarnède system is the second richest subterranean hotspot in France and the first one in Pyrenees. This species richness is, however, expected to increase because several taxonomic groups, like Ostracoda, as well as important subterranean habitats, like MSS (“Milieu Souterrain Superficiel”), have not been considered so far in inventories. Similar levels of subterranean biodiversity are expected to occur in less-sampled karsts of central and western Pyrenees.

In contrast, the eyes of Myriapoda (millipedes and centipedes) are fields of optical units, the lateral ocelli, each of which is composed of up to several hundreds of cells. For many years these striking differences between the lateral eyes of Crustacea/Insecta versus Myriapoda have puzzled evolutionary biologists, as the Myriapoda are traditionally considered to be closely related to the Insecta. The prevailing hypothesis to explain this paradox has been that the myriapod fields of lateral ocelli derive from insect compound eyes by disintegration of the latter into single ommatidia and subsequent fusion of several ommatidia to form multicellular ocelli. To provide a fresh view on this problem, we counted and mapped the arrangement of ocelli during postembryonic development of a diplopod. Furthermore, the arrangement of proliferating cells in the eyes of another diplopod and two chilopods was monitored by labelling with the mitosis marker bromodeoxyuridine.

  • Some Aspects of the Ecology of Millipedes (Diplopoda) Thesis
    Some Aspects of the Ecology of Millipedes (Diplopoda) Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Monica A. Farfan, B.S. Graduate Program in Evolution, Ecology, and Organismal Biology The Ohio State University 2010 Thesis Committee: Hans Klompen, Advisor John W. Wenzel Andrew Michel Copyright by Monica A. Farfan 2010 Abstract The focus of this thesis is the ecology of invasive millipedes (Diplopoda) in the family Julidae. This particular group of millipedes are thought to be introduced into North America from Europe and are now widely found in many urban, anthropogenic habitats in the U.S. Why are these animals such effective colonizers and why do they seem to be mostly present in anthropogenic habitats? In a review of the literature addressing the role of millipedes in nutrient cycling, the interactions of millipedes and communities of fungi and bacteria are discussed. The presence of millipedes stimulates fungal growth while fungal hyphae and bacteria positively effect feeding intensity and nutrient assimilation efficiency in millipedes. Millipedes may also utilize enzymes from these organisms. In a continuation of the study of the ecology of the family Julidae, a comparative study was completed on mites associated with millipedes in the family Julidae in eastern North America and the United Kingdom. The goals of this study were: 1. To establish what mites are present on these millipedes in North America 2. To see if this fauna is the same as in Europe 3. To examine host association patterns looking specifically for host or habitat specificity.

Brief characterization of the group and main diagnostic characters 1.1. Morphology The members of the order Callipodida are best recognized by their putative apomorphies: a divided hypoproct, divided anal valves, long extrusible tubular vulvae, and, as in all other helminthomorph milli- pede orders, a characteristic conformation of the male gonopods. As in Polydesmida, only the first leg pair of the 7th body ring is transformed into gonopods, which are retracted inside the body. Body rings are open ventrally and are not fused with the sternites, leaving the coxae of the legs free. Legs in the anterior half of the body carry coxal pouches. The small collum does not overlap the head. Callipodida are of uniformly cylindrical external appearance. The number of body rings is only sometimes fixed in species and usually exceeds 40. There are nine antennomeres, as the 2nd antennomere of other Diplopoda is subdivided (= antennomere 2 and 3 in Callipodida). The general struc- ture of the gnathochilarium is shared with the Chordeumatida and Polydesmida. Callipodida are said to be characterised by longitudinal crests, which gives the order the common name “crested millipedes”. Although crest are present in most species, some genera (e.g. Schizopetalum) lack a crest, while some Spirostreptida ( e.g. in Cambalopsidae, ‘Trachystreptini’) and some Julida (e.g.

Milne4, Nicholas S. Gladstone5, Annette S. Engel6, John B. Jensen7, Carlos D. Camp8, James C. Ozier9, and Alan Cressler10 Abstract We provide an annotated checklist of species recorded from caves and other subterranean habitats in the state of Georgia, USA. We report 281 species (228 invertebrates and 53 vertebrates), including 51 troglobionts (cave-obligate species), from more than 150 sites (caves, springs, and wells). Endemism is high; of the troglobionts, 17 (33 % of those known from the state) are endemic to Georgia and seven (14 %) are known from a single cave. We identified three biogeographic clusters of troglobionts. Two clusters are located in the northwestern part of the state, west of Lookout Mountain in Lookout Valley and east of Lookout Mountain in the Valley and Ridge. In addition, there is a group of tro- globionts found only in the southwestern corner of the state and associated with the Upper Floridan Aquifer. At least two dozen potentially undescribed species have been collected from caves; clarifying the taxonomic status of these organisms would improve our understanding of cave biodiversity in the state.
