Field Notes

Description:

Olá a todos! Como não sou bom em inglês, escrevo sobre esse ciclo em português, que é o meu primeiro idioma. Há dez dias, vi uma larva de mosca Tachinidae que emergia do abdômen de um besouro Lagria villosa. Eu acredito que a larva foi alojada no intestino do besouro, que engoliu o ovo da mosca quando se alimentou de alguma planta que o continha. Foi muita sorte que eu esteva lá naquele momento com uma câmera. Coletei a pequena larva de cor creme e coloquei em um frasco. Em poucas horas, transformou-se em uma pequena pupa marrom cilíndrica de cerca de 2 mm. Hoje, pela manhã, a mosca surgiu, e eu consegui confirmar sua identificação como a mosca Strongygaster da família Tachinidae, e agora o ciclo está completo.

Habitat:

Besouro hospedando a larva encontrado em meu quintal.

Mas que suerte fue muy oportuna, excelentes fotos y descripción, felicitaciones por ser el SOTD .
Many thanks to everyone. Thanks Christine Y., Daniele and António. Obrigada António, estou muito feliz que algo tão humilde seja o SOTD. Muito obrigada Sergio.
Great spotting Sckel,perfect demonstration of the life cycle,great work,congrats on the well deserved SOTD and thanks for sharing
Parabéns Kel, this thorough life cycle documentation has earned you another Spotting of the Day! "Something different for our Spotting of the Day with a splendid documentation of a tachinid fly life cycle by insect enthusiast and Project Noah member Kel Silva! Kel first spotted a larva emerging from the abdomen of a darkling beettle (Lagria villosa, family Tenebrionidae). She collected the larva, placed it in a jar, and within a few hours it turned into a small cylindrical brown pupa. 10 days later a fly emerged which she was able to identify as Strongygaster sp. (family Tachinidae). Tachinids are a large family of parasitoid and parasitic flies which are of interest in biological control programs. In the case described here parasitism probably occurs through ingestion of the tachinid eggs by the beetle larva.

Many thanks Daniele, this article is very interesting, it's a confirmation that I'm on the right path to identification. Many thanks Christine Y. and ChunXingWong, I'm glad I can share this documentation.
surpreendente! Excelente documentação de um processo tão interessante!
Wow! Splendid spotting! This amazing phenomenon of parasitism is indeed well documented by you. Awesome job!
Fascinating Kel! I did a quick bit of research and found this paper, if you haven't already seen it: http://saspublisher.com/wp-content/uploads/2014/01/SAJB-2119-21.pdf
