Lygaeus kalmii Stål, 1874 | |
Lygaeus kalmii, known as the small milkweed bug or common milkweed bug, is a species of seed bug in the family Lygaeidae. It is found in Central and North America. [1] [2] [3]
Lygaeus kalmii was first formally named in 1874 by Swedish entomologist Carl Stål in his Enumeratio Hemipterorum. [4] [3]
There are two recognized subspecies: [3]
Young nymphs of Lygaeus kalmii are initially fully red, developing black diagonal markings on the pronotum. Adults are orange to red and gray/black, reaching 10 to 12 mm (0.39 to 0.47 in) in length. The head is black with a red spot in the center. The forewings are patterned with a black heart inside of an orange-red X which does not meet in the middle. [2] [5]
The membranous portion of the forewings in the eastern subspecies Lygaeus kalmii angustomarginatus has a narrow white margin, while that of the western L. k. kalmii has white spots and a broader margin. [2]
The small milkweed bug is commonly confused with other black and red or orange insects, including Oncopeltus fasciatus , Lygaeus turcicus , and Lygaeus reclivatus . [6]
Lygaeus kalmii angustomarginatus is found in north temperate regions of North America and is not a migratory insect. [7] Only adults overwinter and they do not begin reproduction until the following April. Females are receptive to males in all seasons. [8] The eggs are laid on milkweed ( Asclepias spp.) in the spring. [2]
Small milkweed bugs' primary sources of nutrients are flower nectar and milkweed seeds. If these food sources are limited, they may feed on other insects. [9]
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 1 mm (0.04 in) to around 15 cm (6 in), and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera.
The boxelder bug, also called box bug, maple bug or, inaccurately, box beetle, is a North American species of true bug. It is found primarily on boxelder trees, as well as maple and ash trees. The adults are about 13 millimetres (0.51 in) long with a dark brown or black coloration, relieved by red wing veins and markings on the abdomen; nymphs are bright red. In 2020, this species invaded Chile, thus becoming an invasive species.
Pyrrhocoridae is a family of insects with more than 300 species world-wide. Many are red coloured and are known as red bugs and some species are called cotton stainers because their feeding activities leave an indelible yellow-brownish stain on cotton crops. A common species in parts of Europe is the firebug, and its genus name Pyrrhocoris and the family name are derived from the Greek roots for fire "pyrrho-" and bug "coris". Members of this family are often confused with, but can be quickly separated from, Lygaeidae by the lack of ocelli on the top of the head.
Geocoris is a genus of insects in the family Geocoridae. Commonly known as big-eyed bugs, the species in Geocoris are beneficial predators, but are often confused with the true chinch bug, which is a pest. There are more than 140 described species in Geocoris.
The Lygaeoidea are a sizeable superfamily of true bugs, containing seed bugs and allies, in the order Hemiptera. There are about 16 families and more than 4,600 described species in Lygaeoidea, found worldwide. Most feed on seeds or sap, but a few are predators.
The Lygaeidae are a family in the Hemiptera, with more than 110 genera in four subfamilies. The family is commonly referred to as seed bugs, and less commonly, milkweed bugs, or ground bugs. However, while many of the species feed on seeds, some feed on sap (mucivory) or seed pods, others are omnivores and a few, such as the wekiu bug, are carnivores that feed exclusively on insects. Insects in this family are distributed across the world. The family was vastly larger, but numerous former subfamilies have been removed and given independent family status, including the Artheneidae, Blissidae, Cryptorhamphidae, Cymidae, Geocoridae, Heterogastridae, Ninidae, Oxycarenidae and Rhyparochromidae, which together constituted well over half of the former family.
Oncopeltus fasciatus, known as the large milkweed bug, is a medium-sized hemipteran of the family Lygaeidae. It is distributed throughout North America, from Central America through Mexico and the Caribbean to southern areas in Canada. Costa Rica represents this insect's southern limit. It inhabits disturbed areas, roadsides, and open pastures. Due to this widespread geographic distribution, this insect exhibits varying life history trade-offs depending on the population location, including differences in wing length and other traits based on location.
Lygaeus equestris, common name Black-and-Red-bug, is a species of ground bugs belonging to the family Lygaeidae, subfamily Lygaeinae.
The Blissidae are a family in the Hemiptera, comprising nearly 50 genera and 400 species. The group has often been treated as a subfamily of the Lygaeidae but was resurrected as a full family by Thomas Henry (1997).
Musgraveia sulciventris is a large stink bug found in Australia, sometimes known as the bronze orange bug. It is considered a pest, particularly to plants in the citrus group. Bronze orange bugs suck the sap from trees, which causes the flowers and fruit to fall.
Oedancala dorsalis is an insect, found in the superfamily Lygaeoidea which is one of the largest varied family of Heteroptera of Hemiptera. Seed bugs are a very diverse family of seed feeders found on various types of vegetation. There are four Nearctic species in this genus. O. bimaculate and O. cubana are neotropical species that barely make it into the United States.
Lygaeus is a genus of seed bugs in the family Lygaeidae. There are more than 60 described species in Lygaeus.
Arocatus melanocephalus, the elm seed bug, is a true bug in the family Lygaeidae. The species was initially described by Johan Christian Fabricius in 1798, and Maximilian Spinola designated it to be the type species of the genus Arocatus in 1837. This bug is native to Europe but has been introduced to North America.
Scantius aegyptius, the Mediterranean red bug, is a species of red bug in the family Pyrrhocoridae, that is a pest of plant species in the family Malvaceae.
Tempyra is a genus of dirt-colored seed bugs in the family Rhyparochromidae. There are at least two described species in Tempyra.
Oncopeltus is a genus of seed bugs in the family Lygaeidae, which has at least 40 described species.
Lygaeus turcicus, the false milkweed bug, is a species of seed bug in the family Lygaeidae. It is found in Eastern North America.
Ischnorhynchinae is a subfamily of seed bugs in the family Lygaeidae. There are about 16 genera and more than 70 described species in Ischnorhynchinae. The members of this subfamily are small, terrestrial insects that typically translucent or transparent plate-like structures covering the thorax (pronota) and tend to live in plant flowers.
Lygaeus creticus is a species of seed bug in the family Lygaeidae. It is found in areas around the Mediterranean Sea.
Lycorma imperialis is a planthopper indigenous to parts of China and Indo-Malaysia. L. imperialis was originally discovered in 1846 by Adam White and has one recognized non-nominate subspecies, L. i. punicea. L. imperialis has undergone a number of reclassifications since its discovery and is one of four species in the genus Lycorma. L. imperialis follows a hemimetabolous life cycle and will undergo a series of nymphal stages (instars) before maturing to an adult.
