The parsnip moth or parsnip webworm (Depressaria radiella) is a moth of the family Depressariidae. It is found in most of Europe, except Portugal and most of the Balkan Peninsula. This species has also been introduced into New Zealand.

Contents

The wingspan is 19–27 millimetres (34–1 in). [2] Adults are on wing from August to (after overwintering in a sheltered place) May of the following year. There is one generation per year.

The larvae feed on Heracleum sphondylium , Pastinaca sativa and Apium nodiflorum . They feed on the flowers and developing seeds, defending their territory by enclosing an umbel in silk, while safely metabolizing the ingested furocoumarins. [3] Pupation takes place in the main stem of the food plant. [4]

Taxonomy

Depressaria radiella is the type species of the genus Depressaria . Its scientific name has been much confused for about 200 years. A.H. Haworth, on establishing the genus Depressaria in his 1811 issues of Lepidoptera Britannica, called the eventual type species Phalaena heraclei, an unjustified emendation of P. (Tortrix) heracliana. In this he followed such entomologists of his time as A.J. Retzius, who in 1783 had believed the parsnip moth to be a species originally described by Carl Linnaeus in 1758. But in fact, this was a misidentification; Linnaeus' moth was actually the one known today as Agonopterix heracliana . To make matters worse, J. Curtis popularized another incorrect spelling, D. heracleana, apparently first introduced (as Pyralis heracleana) by J.C. Fabricius in his 1775 Systema Entomologiae. [5]

When the error of Retzius, Haworth and others was realized, it was assumed that the parsnip moth was only validly described (as Haemilis pastinacella) by P.A.J. Duponchel in 1838, and consequently it was throughout much of the 20th century known as D. pastinacella. But according to the ICZN's judgement, there already was an older valid description that of J.A.E. Goeze, who in 1783 named the species Phalaena radiella. Thus, the correct scientific name of the type species is D. radiella. [5]

Distribution

Introduced

D. pastinacella was first known to be present in North America in 1883. [6] This species has also been recorded in New Zealand in January 2004. [7]

Interactions with hosts

Sphondin - a furanocoumarin - is a chemical produced by some plants. It deters D. pastinacella and higher amounts confer even higher host resistance. Over the time of D. pastinacella's presence in North America, parsnips ( Pastinaca sativa ) have evolved steadily higher amounts of sphondin production. This likely indicates coevolution with D. pastinacella. [6]

<span class="mw-page-title-main">Parsnip</span> Root vegetable in the flowering plant family Apiaceae

The parsnip is a root vegetable closely related to carrot and parsley, all belonging to the flowering plant family Apiaceae. It is a biennial plant usually grown as an annual. Its long taproot has cream-colored skin and flesh, and, left in the ground to mature, it becomes sweeter in flavor after winter frosts. In its first growing season, the plant has a rosette of pinnate, mid-green leaves. If unharvested, it produces a flowering stem topped by an umbel of small yellow flowers in its second growing season, later producing pale brown, flat, winged seeds. By this time, the stem has become woody, and the tap root inedible.

<i>Dyseriocrania subpurpurella</i> Moth species in family Eriocraniidae

Dyseriocrania subpurpurella is a diurnal moth from the family Eriocraniidae, found in most of Europe. The moth was first named by the English entomologist, Adrian Hardy Haworth in 1828.

<i>Orthonama obstipata</i> Species of moth

Orthonama obstipata, the gem, is a moth of the family Geometridae. The species was first described by Johan Christian Fabricius in 1794. It is a cosmopolitan species. In continental Europe though in the northeast, its range does not significantly extend beyond the Baltic region and it is absent from northern Russia. This well-flying species is prone to vagrancy and able to cross considerable distances of open sea; it can thus be regularly found on the British Isles and even on Iceland.

Nemapogon granella is a species of tineoid moth. It belongs to the fungus moth family (Tineidae), and therein to the subfamily Nemapogoninae. It is the type species of its genus Nemapogon, and via that also of the subfamily Nemapogoninae. It is also the type species of the proposed genera Brosis and Diaphthirusa, which are consequently junior objective synonyms of Nemapogon.

<i>Depressaria</i> Genus of moths

Depressaria is a moth genus of the superfamily Gelechioidea. It is the type genus of subfamily Depressariinae, which is often – particularly in older treatments – considered a distinct family Depressariidae or included in the Elachistidae, but actually seems to belong in the Oecophoridae.

<i>Tinea</i> (moth) Genus of moths

Tinea is a genus of the fungus moth family, Tineidae. Therein, it belongs to the subfamily Tineinae. As evident by its name, it is the type genus of its subfamily and family. Established as one of the first subgroups of "Phalaena", it used to contain many species of Tineidae that are nowadays placed in other genera, as well as a few moths nowadays placed elsewhere.

In the 10th edition of Systema Naturae, Carl Linnaeus classified the arthropods, including insects, arachnids and crustaceans, among his class "Insecta". Butterflies and moths were brought together under the name Lepidoptera. Linnaeus divided the group into three genera – Papilio, Sphinx and Phalaena. The first two, together with the seven subdivisions of the third, are now used as the basis for nine superfamily names: Papilionoidea, Sphingoidea, Bombycoidea, Noctuoidea, Geometroidea, Tortricoidea, Pyraloidea, Tineoidea and Alucitoidea.

<i>Agonopterix</i> Genus of moths
