A new species of Tachinid Fly from Ecuador.


Tachinids are a family of True Flies, Diptera, found across the globe. They are noted for their parasitoid life-cycle, in which the larvae of the Flies (maggots) grow inside the living body of a member of a host species, typically another Arthropod, eventually killing the host. Unlike parasitic Wasps, which typically can only infect a single host species, Tachinid Flies are often able to target a range of host species. Tachinids have been found to attack caterpillars (the larvae of Butterflies and Moths), including stem mining species which are hard to access from the exterior of the plant, Sawfly larvae, adult and larval Beetles, True Bugs, Orthopterans (Grasshoppers, Crickets etc.) and even Centipedes.

In a paper published in the journal ZooKeys on 16 December 2014, Diego Inclán of the Università degli Studi di Padova and the Sección Invertebrados at the Museo Ecuatorianode Ciencias Naturales and John Stireman of the Department of Biological Sciences at Wright State University describe a new species of Tachinid Fly from Ecuador, as part of a review of the genus Eucelatoria in tropical Central and South America.

The new species is placed in the genus Eucelatoria and given the specific name flava, meaning ‘yellow’, in reference to the distinctive colour of its abdomen. Eucelatoria flava is described from two male specimens, both from the same locality, 7 km south of Baeza in Napo Province, Ecuador, at an altitude of about 2000 m. These are 6.6-6.7 mm in length, notably hairy and black in colour apart from the distinctive yellow abdomen.

However identifying such behaviour in the fossil record is difficult, and while a variety of parasitic insects are known from Cainozoic deposits, only Fleas are known from the Mesozoic, when...

They have an unusual lifestyle, with the larva maturing within the female Fly (which only produces one larva at a time), then being ‘laid’ during the pupa stage. The female Fly leaves her host Bat to lay this pupa, which hatches 3-4 weeks later, producing a new adult...

California is recognised as an area of exceptional biodiversity, with a wide range of habitats within the boundaries of the state, including the California Floristic Province, which includes many plant species not found elsewhere, such as the Sequoias of the Sierra Nevada, giant Coniferous trees which can reach over 100 m in height. Despite the recognised importance of...
