Black Shield Wasp - Vespa bicolor
This is the
smallest species of Vespa, and certainly one of the smallest in the
world (perhaps the smallest). It is easily recognizable due to its bright
yellow colour; it has a black triangular patch on the central part of the
thorax, and the abdomen sometimes displays black stripes due to expansion when
the wasp is eating. Queens are far larger than workers and reach 25mm or more;
males average 19 to 23mm, and the largest workers reach 22mm. Most workers I
find are in the range of 17 to 19mm, and some only 15mm.
is one of the most common social wasps, along
with species of Parapolybia. It can be found in a wide range of
environments, and frequently appears near human dwellings.
is not at all picky regarding its choice of prey. Workers of this species
target small flying insects, and tend to hunt by site. They are also fond of
human food, particularly meaty items, and frequently appear at barbecue sites.
This is the only local hornet which seems to like collecting cooked meat. It
can thus be a pest at barbecues and outdoor events. They apparently do not hurt
people in their quest for food, and a small number can easily be chased away,
but on occasions, when they appear in large numbers, it can be disastrous. They
especially like the smell of barbequed meats and fish, as well as anything
sweet. They also forage among garbage.
The nest of Vespa
bicolor can be located in a wide variety of locations; under roofs, high in
trees, under rocky ledges, in tree hollows and also frequently underground;
more than 50% of nests have been built either in concealed locations or inside
buildings. It is generally 25 to 35 cm in diameter, and almost always
spherical; it may become slightly oval if the colony did exceptionally well. It
can be distinguished by its shape and light, fine appearance, with numerous
arc-shaped overlapping layers on the outer envelope. This species has an
extremely long life cycle; the queens awake from hibernation as early as
mid-March, and the colony usually dies only in late February or early March.
Therefore, the period in between the death of old colonies and start of new
ones is exceedingly short.
Vespa bicolor is in fact quite gentle; it is seldom
hostile towards movement near the nest, and it is even possible to safely
approach the nest to within a foot or two. However, when provoked, the workers
will ferociously rise to the defense of the colony, although the defended
radius appears relatively small. Despite its small size, it has quite a painful
sting, and the vast numbers in a colony could result in severe consequences.
This, coupled with the fact that it often nests near urban areas, makes it one
of the more dangerous species, but still, conflict is easily avoidable. A nest
will not go unnoticed for long due to the constant stream of workers returning
and leaving (this species has the highest activity level near the nest of any Vespa),
and therefore it is easy to avoid accidentally disturbing a nest. The queens
also frequently hibernate in apartments, and sometimes fly in circles upon
awaking, causing fear or annoyance. They should simply be left alone; with
lights switched off and windows open, they quickly find their way out. Single
queens will never attack.
thorax and gaster slightly pubescent, with stiff erected hairs, and impunctate.
Head : vertex dark brown with finely punctured, fron and temple light
sulphur-yellow; antennae dark brown with underneath and scape light
sulphur-yellow; clypeus light sulphur-yellow, fine punctures, posterior side
with broadly rounded lobes; mandibles light sulphur-yellow with black tooth.
Pronotum light sulphur-yellow, mesonotum black, scutellum and postscutellum
light sulphur-yellow with a medial longitudinal black line, not reaching to the
apex of latter, propodeum light sulphur-yellow, black Y-shaped marked on the
posterior. Legs light sulphur-yellow. Wings light flavo-hyaline with dark brown
color along the costal margin of the forewing, tegulae yellow. Gastral segments
light sulphur-yellow, generally with black-marked on the second and third
segment. This wasp is distinguised from other species by having light
sulphur-yellow color with two black marks on abdomen.
Vespa bicolor is
the smallest species of Vespa: Body length of workers only 15-22 mm, males
19-23 mm and queens reach 25mm.
