Dicyrtomina ornata (Nicolet 1842)

Kingdom: Animalia
Subkingdom: Eumetazoa
Phylum: Arthropoda
Subphylum: Hexapoda
Class: Entognatha
Order: Collembola
Suborder: Symphypleona
Family: Dicyrtomidae
Genus: Dicyrtomina
Species: ornata

Springtails (Order Collembola) form the largest of the three orders of modern hexapods (along with the Protura and Diplura) that are no longer considered insects. The three orders are sometimes grouped together in a class called Entognatha because they have internal mouthparts, but they do not appear to be more closely related to one another than to insects, which have external mouthparts. Recent genetic studies suggest that Collembola are a separate evolutionary line from the other Hexapoda [2][3][4].

Members of Collembola are normally less than 6 mm long, have six or fewer abdominal segments and possess an eversible tubular appendage (the collophore) projecting ventrally from the first abdominal segment. Most species have an abdominal, tail-like appendage, the furcula, that is folded beneath the body to be used for jumping when the animal is threatened. It is held under tension by a small structure called the retinaculum and when released, snaps against the substrate, flinging the springtail into the air.

Suborder Arthropleona has an elongated body, while Symphypleona has a globular body.

Springtails are cryptozoa frequently found in leaf litter and other decaying material [5], where they are primarily detritivores, and one of the main biological agents responsible for the creation of soil. In sheer numbers, they are reputed to be one of the most abundant of all macroscopic animals, with estimates of 100,000 individuals per cubic meter of topsoil, essentially everywhere on Earth where soil occurs; only nematodes, crustaceans, and mites are likely to have global populations of similar magnitude, and each of those groups is of a higher taxonomic rank (nematodes are a phylum, crustaceans a subphylum, and mites are a subclass). Most springtails are small and difficult to see by casual observation, but one species, Hypogastrura nivicola (the so-called snow flea), is readily observed on warm winter days when it is active and its dark color contrasts sharply with a background of snow.

Various sources and publications have suggested that some springtails may parasitize humans, but this is entirely inconsistent with their biology, and no such phenomenon has ever been scientifically confirmed, though it has been documented that the scales or hairs from collembolans can cause irritation when rubbed into the flesh [6]. They can sometimes be abundant indoors in damp places such as bathrooms and basements[1], and under such circumstances may be found on one's person, but this is only accidental.

Hi Jose,very impressive details of this little little insect and very interesting note,thanks for share,Luciano

owards below milimetric scale the efficiency of lenses decreases pretty much. Considering this your results are quite successful. Besides you took it in the natural conditions. Well done!

Hi Jose.
What a crisp sharpness of the main subject of the image. I am sure the insect is tiny. Great DOF and terrific details. Wonderful rich colour palette and very good composition of the shot. Well done and kind regards.

Ciao Jose,
complimenti per questa "super-macro".
Si tratta certamente di una delle foto più nitide che io ho visto fino ad ora di questi microscopici e interessanti insetti, così poco noti alla maggior parte dei macrofotografi.
Grazie per questo interessante contributo.
Cordiali saluti,
Marcello

Hola José Ramón, un excelente documento de este pequeño artrópodo que ni conocía. Sorprendente la gran y buena ampliación así como los colores. La explicación bastante completa.
Abrazo.

Hi Jose, a splendid collembolan insect with lovely details and great sharpness, wonderful light and good colors, very well done.

Hola Jose Ramon!
And this is a real macro! So small object, so mobile (they jump so quickly!!!), and so perfect presented! Bravo, bravo, bavo! Details, shapness and DOF are fantastic! You showed us a very unusual creature from the micro-world!
Best greetings,
Radomir

Ys José,
this macro really deserves to be listed under "Fantastic macros". I know how small the buggers are but you got it all perfectl here, even the background is well suited. Bravo!
Best regards
Dietrich

I have seen this strange creature for the first time, Jose. Looks like it is small insect with delicate limbs.
Very articulate shot, indeed.
TFS and regards.

¡Vaya! Pues para haber tantos colémbolos por metro cuadrado yo nunca me había percatado de ellos. ¡Ni sabía que existían! Sin duda son unos bichillos muy curiosos y diminutos.
Muchísimas gracias por esta foto tan buena y tan bien documentada. Es realmente interesante.
Felicidades y un cordial saludo.
