Jadera haematoloma

Jadera haematoloma, the red-shouldered bug, goldenrain-tree bug or soapberry bug is a species of true bug that lives throughout the United States and south to northern South America. [1] It feeds on seeds within the soapberry plant family, Sapindaceae, and is known to rapidly adapt to feeding on particular hosts. The species is often confused with boxelder bugs and lovebugs.

Description

Jadera haematoloma are typically 9.5–13.5 millimetres (0.37–0.53 in) long and 3–4 millimetres (0.12–0.16 in) wide, though the short-winged form (brachyptera) usually is 7–8 millimetres (0.28–0.31 in) long. Color is mostly blackish (sometimes, bluish grey, or purplish, or bright red immediately after molting) except for red eyes, "shoulders" (lateral margins of pronotum), and costal margins and dorsal part of abdomen. Nymphs are mostly red with a black pronotum and wingpads. All appendages are blackish. [1]

Distribution

For most of the twentieth century, little was known about the range of J. haematoloma. Reports showed breeding populations to be present in Florida, Kansas, Colorado, Texas, Arizona, California, Alabama, Illinois, North Carolina, Missouri, Colorado, Iowa, as well as Georgia, South Carolina, Virginia, Pennsylvania, Maryland, and Royal Oak, Michigan. [2] [3] [4] [5] [6] A study published in 1987 showed the distribution of J. haematoloma and "revealed the close correspondence of records for the bug with the ranges of the soapberry plants that serve as the insects native hosts." [7] In addition, isolated examples have been reported as far north as Minnesota. Outside of the United States, J. haematoloma is found south through Central America and the West Indies to Colombia and Venezuela. [8] [9]

Although native to the New World, the discovery of J. haematoloma populations in Taiwan in 2012 marked the first finding of the species and genus in Asia. [10]

Evolution

Two populations in southern Florida are particularly notable. The more southern of these two populations feeds on the seeds of a native host vine balloon vine ( Cardiospermum corindum ). This vine produces capsules of a fairly uniform size, which adult J. haematoloma feed on by inserting their mouthparts (beak) through the capsule's exterior and into the interior seeds. In the mid-1950s, a related southeast Asian tree, the Taiwanese Flamegold ( Koelreuteria elegans ), was introduced as an ornamental plant. It escaped domestication and naturalized. Significantly, the Flamegold was colonized by J. haematoloma, though its capsules are smaller and the seeds less deeply embedded than in the balloon vine.

In a seminal paper published in the scientific journal Genetica in 2001, it was shown evolution had taken place in this colonizing population of J. haematoloma on the Flamegold in a period of only a few decades. [11] They showed that the beak length, which in the ancestral type was about 70% the length of the body, was only about 50% the body length in the insects that had colonized the non-native tree, though the size of the bugs themselves had not changed. In addition, they found that: [12]

...derived bugs mature 25% more rapidly, are 20% more likely to survive, and lay almost twice as many eggs when reared on seeds of the introduced host rather than those of the native host. Fecundity is also twice as great as that of ancestral type bugs reared on either host, while egg mass is 20% smaller.

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 species of true bug native to eastern North America. The western boxelder bug Boisea rubrolineata is a relative of this species and is native to western North America. Boxelder bugs are found primarily on boxelder trees, as well as on maple and ash trees.

The western conifer seed bug, often mistakenly referred to as stink bug, sometimes abbreviated as WCSB, is a species of true bug (Hemiptera) in the family Coreidae. It is native to North America west of the Rocky Mountains but has in recent times expanded its range to eastern North America, to include Ontario, Québec, New Brunswick, Nova Scotia, Michigan, Maine, Pennsylvania, New York, Connecticut, Massachusetts, and New Hampshire, and has become an accidental introduced species in parts of Europe and Argentina.

<span class="mw-page-title-main">Brown marmorated stink bug</span> Species of Pentatomid insect

The brown marmorated stink bug is an insect in the family Pentatomidae, native to China, Japan, Korea, and other Asian regions. In September 1998, it was collected in Allentown, Pennsylvania, where it is believed to have been accidentally introduced. The nymphs and adults of the brown marmorated stink bug feed on over 100 species of plants, including many agricultural crops, and by 2010–11 had become a season-long pest in orchards in the Eastern United States. In 2010, in the Mid-Atlantic United States, $37 million in apple crops were lost, and some stone fruit growers lost more than 90% of their crops. Since the 2010s, the bug has spread to the nation of Georgia and Turkey and caused extensive damage to hazelnut production. It is now established in many parts of North America, and has recently become established in Europe and South America.

<span class="mw-page-title-main">Serinethinae</span> Subfamily of true bugs

Serinethinae is a subfamily of the hemipteran family Rhopalidae, sometimes known as soapberry bugs. They are brightly colored seed-eaters, comprising three genera and about sixty-five species. These bugs are specialists on plants in the soapberry family (Sapindaceae), which includes maples, balloon vines, and soapberry trees, among others. Seeds of the plants are the main resource used by adults for reproduction and nymphs for growth and development. Their diversity is the result of an adaptive radiation on these plants, whose cyanide-based defenses the bugs have overcome.

<i>Adelphocoris lineolatus</i> Species of true bug

Adelphocoris lineolatus, is commonly known as the Lucerne bug or the alfalfa plant bug, and belongs to the family Miridae. It is an agricultural pest causing vast amounts of damage to numerous crops, but primarily to alfalfa crops around the globe.

<i>Coreus marginatus</i> Species of true bug

Coreus marginatus is a herbivorous species of true bug in the family Coreidae. It is commonly known as the dock bug as it feeds on the leaves and seeds of docks and sorrels. It is a medium-sized speckled brown insect, between 13 and 15 mm long as an adult, with a broad abdomen. It occurs throughout Europe, Asia and northern Africa. It is often found in dense vegetation, such as hedgerows and wasteland.

<i>Boisea</i> Genus of true bugs

Boisea is the least speciose genus of the soapberry bug subfamily. Members of this genus are found in North America, India, and Africa. Unlike other serinethine genera, the distribution of Boisea is very patchy; it is speculated that its highly vicariant range is relictual of what was previously a much vaster, continuous range. The most well-known species of this genus are the North American boxelder bugs and African Boisea fulcrata. The US species mainly feed on the seeds of maple trees and are occasional nuisance pests around homes.

<i>Leptocoris</i> Genus of true bugs

Leptocoris is the largest genus of bugs in the subfamily Serinethinae. Species in this genus are distributed throughout Africa, South Asia, and Oceania and are thought to have originated in Africa, where the greatest diversity of Leptocoris species are found.
