Revisited larval morphology of Thanatophilus rugosus (Coleoptera: Silphidae)

International Journal of Legal Medicine, 2017
Determination of insect species and their instars, occurring on human remains, is important information that allows us to use insects for estimation of postmortem interval and detect possible manipulation with the body. However, larvae of many common species can be identified only by molecular methods, which is not always possible.

Larval cement gland of frogs: Comparative development and morphology

Journal of Morphology, 2005
The cement gland (CG) is a transient mucus-secreting organ, found in most anuran embryos and early larvae and located normally on the anteroventral side of the head. Its sticky secretion allows newly hatched larvae to attach to the egg jelly or to another support and remain hidden and stationary until feeding starts.

Egg and Larval Morphology of Culicoides sonorensis (Diptera: Ceratopogonidae)

Journal of Medical Entomology, 2017
The egg and larval instars (L1-L4) of Culicoides sonorensis Wirth and Jones are described. Average (range) of body lengths of a laboratory colony (Van Ryn) were 0.45 (0.43-0.48) mm for eggs, 0.72 (0.39-0.92) mm for L1, 1.8 (1.3-2.2) mm for L2, 3.6 (2.2-5.0) mm for L3, and 5.9 (5.0-6.9) mm for L4. Head capsule lengths were 0.067 (0.064-0.070) mm for L1,

Larval ecology and morphology in fossil gastropods

Palaeontology, 2014
AbstractThe shell of marine gastropods conserves and reflects early ontogeny, including embryonic and larval stages, to a high degree when compared with other marine invertebrates. Planktotrophic larval development is indicated by a small embryonic shell (size is also related to systematic placement) with little yolk followed by a multiwhorled shell ...

Classification of Screwworms (Diptera: Calliphoridae) by Larval Spine Morphology

Journal of Medical Entomology, 1990
The morphology of screwworm, Cochliomyia hominivorax (Coquerel), larval spines was affected by larval substrate and geographic effects on variation. Spine morphology of individual larvae was used to determine criteria for discrimination analysis classification. Classification criteria for types of wounds and host species were determined for larvae from

Functional morphology of the pretarsus in larval Thysanoptera

Canadian Journal of Zoology, 1972
Legs of larval thrips differ in form and function from those of the adults. The tarsal depressor muscle and tibial gland of the adult are absent, the trochanter and tarsus are fused to the femur and tibia, respectively, and the relative sizes and shapes of the remaining parts differ.Contraction of the pretarsal depressor muscle elevates and flattens ...

Shell morphology of larval and post-larval mytilids from the north-western Atlantic

Journal of the Marine Biological Association of the United Kingdom, 1989
Comparison of early shell morphological features of six mytilids from the north-western Atlantic revealed differences useful for species identification and classification. Brachidontes exustus, lschadium recurvum, Geukensia demissa, Amygdalum papyrium, Mytilus edulis, and Modiolus modiolus larvae and post-larvae were cultured in the laboratory ...

Functional morphology of gills in larval amphibians

1984
Scanning electron microscopy and vascular casting were used to study the morphology and vascular anatomy of the fully developed internal gills of Litoria ewingi tadpoles and the external gills of mexican axolotls, Ambystoma mexicanum.

Morphology of the Microfilaria of Brugia pahangi and of the Larval Stages in the Mosquito

The Journal of Parasitology, 1962
The detailed morphology of the microfilariae of B. pahangi following several methods of preparation is described. Possible features which will allow its rapid differentiation from the microfilariae of B. malayi and of B. patei are the size and proportions of the cephalic space.

On the Morphology of the Chondrocranium of the Larval Herring (Clupea harengus)

Proceedings of the Zoological Society of London, 2009
Summary. 1 The hyomandibular, quadrate, symplectic, and styIohyoid are, in the 5 mm. stage, all one mass of cartilage. 2 This mass is fused, at this stage, to the cranial cartilage and to Meckel's cartilage. 3 The palato-pterygoid forms at about 13 mm., and grows back to meet the quadrate. 4 Until the 20 mm. stage is reached, the brain
