Burnettweldia Plumbella
''Burnettweldia plumbella'', also known as the beaked twig gall wasp, is a species of gall wasp. Previously in the genus '' Disholcaspis'', it was moved into a new genus, ''Burnettweldia'', in 2021. This wasp induces galls on oak trees, including blue oak, leather oak, Muller's oak, and scrub oaks. The galls are up to 15 mm in diameter and brightly colored, coming in either red with yellow spots or green with yellow spots. Their name comes from the galls' pointed tip. Galls are formed in spring and summer, and adults emerge from them in November and December. The adult wasps are 3–4 mm in length.

Gall Wasp
Gall wasps, also incorrectly called gallflies, are hymenopterans of the family Cynipidae in the wasp superfamily Cynipoidea. Their common name comes from the galls they induce on plants for larval development. About 1,300 species of this generally very small creature (1–8 mm) are known worldwide, with about 360 species of 36 different genera in Europe and some 800 species in North America. Features Like all Apocrita, gall wasps have a distinctive body shape, the so-called Petiole (insect anatomy), wasp waist. The first abdominal tergum (the propodeum) is conjoined with the Thorax (insect anatomy), thorax, while the second abdominal segment forms a sort of shaft, the Petiole (insect anatomy), petiole. The petiole connects with the gaster (insect anatomy), gaster, which is the functional abdomen in apocritan wasps, starting with the third abdominal segment proper. Together, the petiole and the gaster form the metasoma, while the thorax and the propodeum make up the mesosoma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disholcaspis
''Disholcaspis'' is a genus of gall wasps in the family Cynipidae. There are more than 40 species described in the genus ''Disholcaspis''. Some ''Disholcaspis'' species induce galls that produce honeydew, a sweet liquid that attracts yellow jackets, ants, and bees. These insects then protect the galls from parasitic wasps. Species These 42 species belong to the genus ''Disholcaspis'': * '' Disholcaspis acetabula'' (Weld, 1921) * '' Disholcaspis bassetti'' (Gillette, 1888) * '' Disholcaspis bettyannae'' Medianero & Nieves-Aldrey, 2011 * '' Disholcaspis bisethiae'' Medianero & Nieves-Aldrey, 2011 * '' Disholcaspis brevinota'' Weld, 1921 * '' Disholcaspis canescens'' Weld, 1957 - Round honeydew gall wasp * '' Disholcaspis cinerosa'' ( Bassett, 1881) - Mealy oak gall wasp * '' Disholcaspis colorado'' Gillette, 1893 * '' Disholcaspis costaricensis'' Melika & Pujade-Villar, 2021 * '' Disholcaspis crystalae'' Pujade-Villar, 2018 * '' Disholcaspis edura'' Weld, 1957 * '' Disholcaspis el ...

Quercus Douglasii
''Quercus douglasii'', known as blue oak, is a species of oak endemic to (and found only in) California, common in the Coast Ranges and the foothills of the Sierra Nevada. It is California's most drought-tolerant deciduous oak, and is a dominant species in the blue oak woodland ecosystem. It is occasionally known as mountain oak and iron oak. Description ''Quercus douglasii'' is a medium-sized tree with sparse foliage, generally tall, with a trunk in diameter at breast height. Trunks are typically solitary, but some trees have multiple trunks. The tallest recorded specimen was found in Alameda County, at . The trees grow slowly, about per year. Individual trees over 500 years old have been recorded. The bark is light gray with many medium-sized dark cracks. The blue-green leaves are tough and leathery, deciduous, long, and entire or shallowly lobed. The acorns are long, with a moderately sweet kernel, and mature in 6–7 months from pollination. ''Q. douglasii'' is mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Durata
''Quercus durata'', commonly known as leather oak, is a species of oak endemic to California, common in the California Coast Ranges, Coast Ranges and the foothills of the Sierra Nevada. The common name "leather oak" is derived from the leathery texture on the lop of its leaves. Taxonomically it is placed in the white oak group (subgenus ''Quercus'', section ''Quercus''). Description As described by English horticulturist and botanist Theodore Payne, leather oak is "A rather low spreading shrub with rigid branches, foliage rich deep green. Desirable for hillside planting." ''Quercus durata'' is a short species of oak generally growing to in diameter with a height of about . In more extreme cases they have been known to grow to be 3–4 m across. The gray or yellowish twigs have scaly Bark (botany), bark and are about in diameter with the trunk diameter reaching 4–5 cm; the branches can be densely or sparsely distributed. The buds are smooth brown or reddish brown ovals. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Cornelius-mulleri
''Quercus cornelius-mulleri'' is a North American species of oak known by the common name Muller oak, or Muller's oak. It was described to science in 1981 when it was segregated from the ''Quercus dumosa'' complex and found to warrant species status of its own. It was named after ecologist Cornelius Herman Muller. It is native to southern California and Baja California, where it grows in chaparral, oak woodlands, and other habitat in foothills and mountains. It can most easily be observed in Joshua Tree National Park and in the woodlands along the western margins of the Colorado Desert in San Diego County, California.Nixon, K. C. (2002)The Oak Biodiversity of California and Adjacent Regions. US Forest Service Gen. Tech. Report Description ''Quercus cornelius-mulleri'' is a bushy shrub not exceeding 3 meters (10 feet) in height. It is densely branched, its tangled twigs gray, brown, or yellowish, fuzzy when new and becoming scaly with age. The evergreen leaves are leathery an ...
