Hydrophilidae Latreille, 1802 (Insecta: Coleoptera) is the most diverse family of Polyphaga with aquatic representatives. Larvae found in association with adult beetles are assigned to the same species and described as such. This is the first description of the larval morphology of the hydrophilid genus Psalitrus d’Orchymont, 1919, as well as the first description of larval chaetotaxy of the tribe Omicrini. Wer sich eine Weile intensiver mit Käfern beschäftigt hat, braucht normalerweise keine Bestimmungstabelle der Familien mehr. Des erste Hinterleibssternit wird nicht vollständig von den Hinterhüften durchsetzt, der Hinterrand desselben ist hinter den Hüften erkennbar, Larvenförmige Imagines; weder Flügeldecken noch Flügel sind vorhanden, auch keine Andeutungen davon, Nicht larvenförmig oder wenigstens mit angedeuteten Flügeldecken. Hintertarsen 5-gliedrig. Males use calling signals under water to find mates. - Deutsche Namen wurden nur verwendet, wenn sie im normalen Sprachgebrauch eingebürgert sind, z.B. 101 (4): 629-636, 2004 | DOI: 10.14411/eje.2004.086. Descriptions of the egg case and larva of Anacaena and a review of the knowledge and relationships between larvae of Anacaenini (Coleoptera: Hydrophilidae: Hydrophilinae) Miguel ARCHANGELSKY 1, Martin FIK EK 2 1 CONICET-LEA, Laboratorio de Ecolog a Acu tica, Universidad Nacional de La Patagonia, San Juan Bosco, Sarmiento … hydrophilid larva is much simpler, usually, than obtaining similar informa-tion from dytiscid material, since hydrophilids have macerating instead of suctorial mandibles and it is often possible to retrieve recognizable material from the gut contents for analysis. They are generally predators, however some eat algae. The size of the Water Scavenger Beetle … Grant No. A good variety of species can be found by collecting in these habitats throughout the year. Nicht fliegenförmig, Flügeldecken nicht schwingkölbchenartig. Adults are generally small, 0.5-3 mm; antennae with a 5-segmented club; maxillary palps may be as long as the antennae, or longer in Hydraena; pronotum may have clear border in other genera. The phylogeny and evolutionary history of the water scavenger beetles (Coleoptera: Hydrophilidae) are inferred from comprehensive analyses of DNA sequence data from the mitochondrial genes COI, COII and 16S and the nuclear genes 18S, 28S and arginine kinase. Includes many common wetland and dung pasture species. Bei hoher Vergrößerung (40-100fach) erkennt man aber an der Basis des Klauengliedes ein winziges abgeteiltes Glied, das zwischen den Seitenlappen des 3. Compared with the larvae of the Hydradephaga, most of the aquatic Hydrophilidae larvae lack channeled mandibles (except Berosus), and they lift their prey out of the water during feeding. These photos supplement pages 145-158 of the Guide to Aquatic Invertebrates of the Upper Midwest. Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae. (Vorsicht: es kommt vor, daß Tiere beim Abtöten die Flügel vorstrecken und nicht mehr zusammenlegen können.). A key to the Sperchopsini genera on the basis of the larval characters is provided.

A key to the larvae, pupae and adults of the British species of Elminthidae. Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae. Females of some genera carry their eggs beneath their abdomen but most females enclose their eggs within a densely woven silk cocoon with one end drawn out into an elongate mast that helps with respiration.

The majority of species are found in freshwater habitats such as ponds, pools, dams, wetlands, lakeshores and streams. Hydrophilidae are relatively poor swimmers and move their legs alternately, unlike the stronger Dytiscidae which use the legs together like oars. This species is compared with other Eurasian representatives of the genus Hydrobius Leach, 1815. Mandibles move horizontally; head complete or, if not, the posterior portion with deep longitudinal incisions, or the thorax and abdomen together consisting of 13 segments of the key larvae either lacking legs, or whose legs are vestigial, although he is fully aware that such a division is not scientific, separating a SPHAERIDIINAs it does the E from the rest of HYDROPHILIDAE the and th, LAMIINAe froEm the other members of the CERAMBYCIDAE Ther.

Several of the former subfamilies of Hydrophilidae have recently been removed and elevated to family rank; Epimetopidae, Georissidae, Helophoridae, Hydrochidae, and Spercheidae. ...Corylophidae. The larvae prey upon small invertebrates such as insects and snails, but can also consume tadpoles and small fish (Cranshaw 2010). Hydrophilidae species over winter mostly as adults, although larvae may still be collected throughout winter. Larvae are usually predacious and feed on other invertebrates and on some small vertebrates. 1.

In contrast to the aforementioned Dytiscidae and Elmidae, food preferences differ between adults and larvae in Hydrophilidae: larvae are always predatory, feeding on various invertebrates, but adults are generally detritivorous, feeding on decaying organic matter, although precise food preferences are known in neither adult nor larval stage for most taxa (e.g. Morphology and chaetotaxy of these larvae is compared to that of Cercyon convexiusculus Stephens, 1829. Representatives of the family lay their eggs wrapped in a silk case with a variety of shapes, sizes, and number of eggs though usually constant for each species. JÄCH & JI (eds.
