Symmorphus Cristatus
''Symmorphus cristatus'' is a species of mason wasp in the subfamily Eumeninae within the family Vespidae. This species is widely distributed in North America, and it preys on the larvae of leaf beetles. Description ''Symmorphus cristatus'' is one of three ''Symmorphus'' species that occur in North America. Viewed from above, the metasomal tergum is narrower than ''S. albomarginatus'' or ''S. canadensis'', and it has smaller depressions (cephalic foveae) adjacent to the simple eyes (ocelli) that are spaced closer together than those of ''S. canadensis.'' The 'femur' portion of the hind legs has conspicuous hairs, which ''S. canadensis'' lacks. Wing length of ''S. cristatus'' ranges from 5.0-9.0mm, and body markings range from pale to yellow. Males are typically about 20% smaller than females, and males typically possess a large pale spot on the ventral part of the face (clypeus) just above the mandibles, whereas in females the spot is small or absent.

Eumeninae
Potter wasps (or mason wasps), the Eumeninae, are a cosmopolitan wasp group presently treated as a subfamily of Vespidae, but sometimes recognized in the past as a separate family, Eumenidae. Recognition Most eumenine species are black or brown, and commonly marked with strikingly contrasting patterns of yellow, white, orange, or red (or combinations thereof), but some species, mostly from tropical regions, show faint to strong blue or green metallic highlights in the background colors. Like most vespids, their wings are folded longitudinally at rest. They are particularly recognized by the following combination of characteristics: # a posterolateral projection known as a parategula on both sides of the mesoscutum; # tarsal claws cleft; # hind coxae with a longitudinal dorsal carina or folding, often developed into a lobe or tooth, and; # fore wings with three submarginal cells. Biology Eumenine wasps are diverse in nest building. The different species may either use existi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Angelica Capitellata
''Angelica capitellata'', synonym ''Sphenosciadium capitellatum'', is a species of flowering plant in the family Apiaceae. When treated as ''Sphenosciadium capitellatum'', it was the only species in the monotypic genus ''Sphenosciadium''. It is known by the common names woollyhead parsnip, ranger's buttons, button parsley, and swamp white heads. Description It is a stout perennial herb growing from a tuberous root and producing an erect stem often exceeding tall and sometimes reaching overall. The stem and leaves are usually green but sometimes nearly white in color, smooth below but with rough hairs on the inflorescence. The leaves are long and divided into several segments which bear widely spaced leaflets. The leaflets may also be intricately divided into small segments. The inflorescence is a whitish compound umbel about across, with many branches. It blooms from July to August. The nearly spherical, headlike terminal umbellets contain many tiny white or purple-tinged ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Daucus Carota
''Daucus carota'', whose common names include wild carrot, European wild carrot, bird's nest, bishop's lace, and Queen Anne's lace (North America), is a flowering plant in the family Apiaceae. It is native to temperate regions of the Old World and was naturalized in the New World. Domesticated carrots are cultivars of a subspecies, ''Daucus carota'' subsp. ''sativus''. Description The wild carrot is a herbaceous, somewhat variable biennial plant that grows between tall, and is roughly hairy, with a stiff, solid stem. The leaves are tripinnate, finely divided and lacy, and overall triangular in shape. The leaves are long, bristly and alternate in a pinnate pattern that separates into thin segments. The flowers are small and dull white, clustered in flat, dense umbels. The umbels are terminal and about wide. They may be pink in bud and may have a reddish or purple flower in the centre of the umbel. The lower bracts are three-forked or pinnate, which distinguishes t ...

Foeniculum Vulgare
Fennel (''Foeniculum vulgare'') is a flowering plant species in the carrot family. It is a hardy, perennial herb with yellow flowers and feathery leaves. It is indigenous to the shores of the Mediterranean but has become widely naturalized in many parts of the world, especially on dry soils near the sea-coast and on riverbanks. It is a highly flavorful herb used in cooking and, along with the similar-tasting anise, is one of the primary ingredients of absinthe. Florence fennel or finocchio (, , ) is a selection with a swollen, bulb-like stem base that is used as a vegetable. Description ''Foeniculum vulgare'' is a perennial herb. It is erect, glaucous green, and grows to heights of up to , with hollow stems. The leaves grow up to long; they are finely dissected, with the ultimate segments filiform (threadlike), about wide. (Its leaves are similar to those of dill but thinner.) The flowers are produced in terminal compound umbels wide, each umbel section having 2 ...

Parasyrphus Melanderi
''Parasyrphus melanderi'' is a flower fly (family Syrphidae) that is best known as a larval predator on the leaf beetle ''Chrysomela aeneicollis'' in the Sierra Nevada range of California. Description Adults are medium-sized flies (approximately 6-11mm). The dorsal side of the fourth abdominal segment (and usually the third segment) have an entire yellow band (rather than black), and the face has a black median stripe. In males, the ventral side of the abdomen (sternites) has few or no distinct markings, and in females, the sternites have spots or triangles and the facial stripe is no more than one-quarter the as wide as the face. Eggs of ''P. melanderi'' are white and are smaller than the eggs of their prey ''Chrysomela aeneicollis'' in California. Mature ''P. melanderi'' larvae are 14–16mm long and approximately 3mm in diameter. Larvae have pale markings with thin dark brown stripes anterior to them.

Chrysomela
''Chrysomela'' is a genus of leaf beetles found almost throughout the world, but not in Australia. It contains around 40 species, including 7 in eastern and northern Europe. It also includes at least 17 species in North America, including the cottonwood leaf beetle '' Chrysomela scripta''. Taxonomy ''Chrysomela'' is traditionally broken up into three subgenera, ''Chrysomela'', ''Macrolina'' (or ''Strickerus'') and ''Pachylina''. In 1998, researchers Maurizio Biondi and Mauro Daccordi proposed a new classification of ''Chryomela'' without any subgenera. This was followed by the sixth volume of the ''Catalogue of Palaearctic Coleoptera''. Species These 28 species belong to the genus ''Chrysomela'': * ''Chrysomela aeneicollis'' (Schaeffer, 1928) * ''Chrysomela collaris'' Linnaeus, 1758 ** ''Chrysomela collaris alpina'' Zetterstedt, 1838 ** ''Chrysomela collaris blaisdelli'' (Van Dyke, 1938) ** ''Chrysomela collaris collaris'' Linnaeus, 1758 ** ''Chrysomela collaris hyperborea'' Me ...

Vespidae
The Vespidae are a large (nearly 5000 species), diverse, cosmopolitan family of wasps, including nearly all the known eusocial wasps (such as ''Polistes fuscatus'', ''Vespa orientalis'', and ''Vespula germanica'') and many solitary wasps. Each social wasp colony includes a queen and a number of female workers with varying degrees of sterility relative to the queen. In temperate social species, colonies usually last only one year, dying at the onset of winter. New queens and males (drones) are produced towards the end of the summer, and after mating, the queens hibernate over winter in cracks or other sheltered locations. The nests of most species are constructed out of mud, but polistines and vespines use plant fibers, chewed to form a sort of paper (also true of some stenogastrines). Many species are pollen vectors contributing to the pollination of several plants, being potential or even effective pollinators, while others are notable predators of pest insect species.
