Euceraphis Betulae
''Euceraphis betulae'', the birch aphid or silver birch aphid, is a species of aphid in the order Hemiptera. It is a tiny green insect with a soft body and wings. It is found living on the European silver birch tree ('' Betula pendula'') where it feeds and multiplies on the buds and leaves by sucking sap. Description The silver birch aphid is a light green colour with a bluish tinge. The blueness is due to the dusting of blue wax particles which are particularly obvious on the antennae and legs. All adults have membranous wings and during the spring and summer, all individuals are female. The mouthparts are specialised to form a slender stylet for piercing and sucking sap from their host tree. Biology Eggs that have overwintered on birch twigs hatch out in the spring. The nymphs feed on the leaf buds as they burst and on tender young leaves. They grow rapidly into winged females that, as soon as they are adults, start to reproduce by parthenogenesis, producing live youn ...

Euceraphis Punctipennis
''Euceraphis punctipennis'', the downy birch aphid or European birch aphid, is a species of aphid in the order Hemiptera. These aphids are tiny green insects with soft bodies and membranous wings. They are found living on downy birch trees ('' Betula pubescens'') where they feed and multiply on the buds and leaves by sucking sap. Description The downy birch aphid has a pale green body, lightly dusted with bluish wax particles, membranous wings and long legs. During the spring and summer all adults are females and give birth to live young by parthenogenesis. This aphid is very similar in appearance to its close relative the silver birch aphid (''Euceraphis betulae'') which lives and feeds exclusively on silver birch trees '' Betula pendula''. At one time they were thought to be the same species but chromosomal differences between the two have been found and they are now considered to be separate species. Distribution This aphid is found in Europe wherever its host trees grow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

True Bugs
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as ants, bees, beetles, or butterflies. In some variations of English, all terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles. The term is al ...

Aphididae
The Aphididae are a very large insect family in the aphid superfamily ( Aphidoidea), of the order Hemiptera. These insects suck the sap from plant leaves. Several thousand species are placed in this family, many of which are considered plant/crop pests. They are the family of insects containing most plant virus vectors (around 200 known) with the green peach aphid (''Myzus persicae'') being one of the most prevalent and indiscriminate carriers. Evolution Aphids originated in the late Cretaceous about (Mya), but the Aphidinae which comprises about half of the 4700 described species and genera of aphids alive today come from their most recent radiation which occurred in the late Tertiary less than 10 Mya.Von Dohlen CD, Moran NA (2000) Molecular data support a rapid radiation of aphids in the Cretaceous and multiple origins of host alternation.
