Face of a southern yellowjacket (Vespula squamosa)Yellowjackets may be confused with other wasps, such as hornets and paper wasps such as Polistes dominula.A typical yellowjacket worker is about 12 mm (0.47 in) long, with alternating bands on the abdomen; the queen is larger, about 19 mm (0.75 in) long (the different patterns on their abdomens help separate various species).
The eastern yellow jacket or eastern yellowjacket (Vespula maculifrons) is a wasp found in eastern North America. [1] Although most of their nests are subterranean, they are often considered a pest due to their nesting in recreational areas and buildings. [ 2 ]
The species has been described as an invasive species. [3] German yellowjackets are known to be especially successful and destructive invaders of new territories. These wasps are polyphagous predators which feed on native arthropods , and because they are able to outdo many other animals for food, they have caused considerable harm to the ...
Vespula squamosa, or the southern yellowjacket, is a social wasp.This species can be identified by its distinctive black and yellow patterning and orange queen. [1] This species is typically found in eastern North America, and its territory extends as far south as Central America. [1]
Adult Cryptophagus pilosus, a species of beetle, has been found in some Vespula atropilosa nests. [9] In autumn they were present in small numbers of about 1 to 8 per nest. [ 9 ] Larvae of C. pilosus were not found in nests in the field but were produced in large numbers in V. atropilosa colonies that were transplanted into screenhouses. [ 9 ]
In these species, haploids are male and diploids heterozygous at the sex locus are female, but occasionally a diploid will be homozygous at the sex locus and develop as a male, instead. This is especially likely to occur in an individual whose parents were siblings or other close relatives. Diploid males are known to be produced by inbreeding ...
What do you call them: firefly or lightning bugs? It turns out they are the same insect! We explain the regional difference in how they are named in America.
Because relatedness differs in haplodiploid species, the effects of kin selection are predicted to differ from that of a diploid species. V. pensylvanica is a haplodiploid species. Thus, female offspring have a 0.75 relatedness to their sisters, but only a 0.25 relatedness to their brothers.
