Hi


* locality - Pedra Cavaleira - Silgueiros - Viseu - PORTUGAL
* date - 13.11.2006
* size - 2 mm - 3 mm (very small flies)
* habitat - woodland
* substrate - Acacia sp.


The right one seems to be a Chironomidae fly... the left one I don?t have an idea..
The spider seems to be a Theridion sp. It could be too Kochiura aulica. :)

Thank you.

Hallo Jorge,
The two preys of the spider are not Diptera.
Both are Homoptera, and the family is Psylloidea (Psyllids)
Look at this: http://www.psyllids.org/

Four wings (well visible in top specimen, right fore extended, right hind over abdomen), way the wings are held (bottom specimen, roof-like) wing venation, broad head with flattened dorsal surface, etc.
