On October 17, 2019 in the south of France.
This small fly, 2 mm long, got caught in the web of a spider Araneus diadematus. Its legs are very long but half of them are stuck in the wires.
Is it possible to determine a gender?

Female in supertribe Cecidomyiidi. They often perch safely on spider webs but this one appears stuck.

If you experienced a very sluggish site recently, it may have been because someone tried to upload a maliciuous script by force. It appears to have failed. The visitor was blocked further access.
