If you go down to the woods today, you might just come across these bristly little flies called Tachina lurida. These ones were in Chicksands Wood in Bedfordshire earlier. #Tachinidae #Diptera

De #Peleteria_rubescens #Tachinidae is een roodbruin gekleurde parasitaire vlieg. Ze leeft in bossen en graslanden en legt haar eieren op rupsen, waarin de larven zich ontwikkelen. De soort helpt zo bij natuurlijke plaagbestrijding.
FIVE (5!) #Tachinidae species NEW TO SCIENCE, described from #Mongolia.
On top of it, 67 species are recorded for the first time from Mongolia.
Not only are our expeditions fun, they deliver important additions to the knowledge of Mongolian #entomofauna.

infographic of new genus and species of ACG parasitic fly, Santarosamyia woodorum. Images within the infographic show the various orientations of the type and paratype individuals for the new species, phylogenies of how this taxon relates to other species within the same subfamily and an image of the DNA barcode variation present within the new species other morphologically similar species.
screen grab of the etymology and ecology of the new species Etymology Santarosamyia woodorum sp. nov. is named in honour of Dr. D. Monty Wood (1933–2020) and Grace Wood for their many years of dedication to the study of Diptera and, in particular, the family Tachinidae of ACG. Their legacy lives in Monty's invaluable contributions to science and the countless people he educated and collaborated with. Interim species-specific names for Santarosamyia woodorum sp. nov., included in previously circulating databases and publications, are tachinidWood12 Wood01 and Nilea Wood01. Distribution Costa Rica, ACG, Guanacaste Province, 20–326 m elevation. Ecology Santarosamyia woodorum sp. nov. has been reared twelve times from at least two species of Lepidoptera in the family Crambidae: Omiodes cuniculalis Guenée, 1854 (n = 3), Eulepte Janzen06 (n = 1) and Eulepte concordalis Hübner, 1825 (n = 7) and one species in the family Pyralidae: Chloropaschia granitalis (C. Felder, R. Felder & Rogenhofer, 1875) (n = 1) in dry fo rest, at elevations ranging from 20–326 m.

bipartite diagram showing the host-specificity of ACG tachinids in the genus Belvosia. Species in red were formerly known as one species that is now known to be three by host-use and genetics. Where formalised names exist, they are largely honoring ACG paraxonomists.
Venn diagram of the overlap between the diversity of ACG tachinids known from rearing larval lepidoptera versus those that are collected in Malaise traps. Only 18.5% overlap.
Evident decline in the abundance of tachinid parasaitoids (here counts/year for the two most abundant subfamilies) in ACG after the stabalisation of the parataxonomist collection workforce in ~2005

Eine schwarze, borstig behaarte Erdwanzenfliege (Phania funesta) sitzt auf einer weißen Zaunwindenblüte. Die Fliege hat große, dunkle Facettenaugen und durchsichtige Flügel mit deutlich sichtbaren Adern. Ihr robuster, gedrungener Körper ist mit zahlreichen schwarzen Borsten bedeckt, die charakteristisch für diese Tachinidae-Art sind.
Detailaufnahme einer Erdwanzenfliege (Phania funesta) von oben auf weißer Zaunwindenblüte. Die Fliege zeigt ihre typischen Merkmale: den glänzend schwarzen, stark beborsteten Körper, die großen braunen Komplexaugen und die transparenten Flügel mit goldbrauner Aderung. Die kräftigen Beine und die dichte Beborstung des Thorax und Abdomens sind gut erkennbar.
Erdwanzenfliegen (Phania funesta) legen ihre Eier an Erdwanzenlarven ab, die sie parasitieren. Die Bilder, die an derselben Blüte an aufeinanderfolgenden Tagen entstanden sind, zeigen vermutlich dasselbe Exemplar.

Pixelart illustration of a large black bristlefly. This type of fly is known for having long bristles, which can be seen here on the tip of the abdomen. The fly has a large black fuzzy body with tattered wings and a lighter coloured head. It sits with its wings spread out and its front legs pointed forward. Some detail resembling droplets drop from the wings and abdomen.
I like bristleflies
