Olpodiplosis
''Olpodiplosis'' is a monotypic genus of gall midges, insects in the family Cecidomyiidae. The only described species is '' Olpodiplosis helianthi''. This species occurs in North America and induces flask-shaped galls on several species of sunflower. The inducers over-winter in the galls, emerging as adults the following spring. The species was first described as ''Diplosis helianthi'' by entomologist William Brodie in 1894, but moved to ''Olpodiplosis'' by Raymond Gagné Raymond J. Gagné (born August 27, 1935) is an American entomologist whose work focuses on gall midges. He was born in Meriden, Connecticut, and earned degrees from the University of Connecticut, Iowa State University, and the University of Min ... in 1973.

Cecidomyiinae
The Cecidomyiinae, commonly known as gall midges or gall gnats, is the largest subfamily in Cecidomyiidae with over 600 genera and more than 5000 described species. Some of the herbivorous species are inquilines, developing in galls that were initiated by a different midge species. Most species in the genus '' Macrolabis'' and the tribes Trotteriini and Camptoneuromyiini are inquilines, but there are also many inquiline species in genera that are predominantly gall-inducing (such as '' Dasineura'' and '' Lasioptera''). Predatory and parasitoid species comprise about 12% of the Cecidomyiinae. Larvae of these species attack other arthropods - there are known predators of mites, aphids, scale insects, dragonfly eggs, and endoparasitoids of Hemiptera. Most are found in the tribes Aphidoletini and Lestodiplosini. Fungivores make up much of the remainder of the subfamily, indicating the retention of (or reversion to) the ancestral food source.

William Brodie (naturalist)
William Brodie (1831 – 6 August 1909) was a Canadian dentist and naturalist. Brodie influenced many naturalists in North America and was involved in establishing the Toronto Entomological Society in 1877 which became in 1878 the Natural History Society of Toronto. In 1885 it became part of the Canadian Institute. He was especially known for his study of plant galls of which he made a large reference collection and described several gall-making insect species. The Brodie Club was established in his memory in 1921. Life and work Brodie was born in Peterhead, Scotland to George and Jean Milne. He was baptized on July 9, 1831. The family moved to Canada when he was four and settled in a farm near Gormley in Whitchurch Township. Brodie grew up with an interest in the natural world nurtured by his mother and went to local schools before teaching in Whitchurch and Markham. One of the earliest students of the Dental College in Toronto, he qualified as a dentist in 1870 after pass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of Genus, genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

Cecidomyiidae
Cecidomyiidae is a family of diptera, flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls. Cecidomyiidae are very fragile small insects usually only in length; many are less than long. They are characterised by hairy wings, unusual in the Order (biology), order Fly, Diptera, and have long Antenna (biology), antennae. Some Cecidomyiids are also known for the strange phenomenon of paedogenesis in which the larval stage reproduces without maturing first. In some species, the daughter larvae consume the mother, while in others, reproduction occurs later on in the egg or pupa. More than 6,650 species and 830 Genus, genera are described worldwide, though this is certainly an underestimate of the actual diversity of this family. A Metabarcoding, DNA metabarcoding study published in 2016 estimated the fauna of Canada alone to be in excess of 16,000 species, hinting at a st ...

Gall
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls can be such highly organized structures that their cause can be determined without the actual agent being identified. This applies particularly to insect and mite plant galls. The study of plant galls is known as cecidology. Anatomy Shape and size Galls develop on various plant organs, providing nutrition and shelter to inducing insects. Galls display vast variation in morphology, size, and wall composition. The size of insect galls can range significantly, from approximately two inches in diameter to less than one-sixteenth of an inch. Some galls are so small that they are merely slightly thick ...

Helianthus
''Helianthus'' () is a genus comprising around 70 species of annual and perennial flowering plants in the daisy family Asteraceae commonly known as sunflowers. Except for three South American species, the species of ''Helianthus'' are native to North America and Central America. The best-known species is the common sunflower (''Helianthus annuus''). This and other species, notably Jerusalem artichoke (''H. tuberosus''), are cultivated in temperateness, temperate regions and some tropical regions, as food crops for humans, cattle, and poultry, and as ornamental plants. The species ''H. annuus'' typically grows during the summer and into early fall, with the peak growth season being mid-summer. Several perennial ''Helianthus'' species are grown in gardens, but have a tendency to spread rapidly and can become aggressive. On the other hand, the whorled sunflower, ''Helianthus verticillatus'', was listed as an endangered species in 2014 when the U.S. Fish and Wildlife Service issued ...
