Once I couldn't reset my (whole house) RCD and by a process of
elimination traced it to the central heating boiler that was in a
brick lean-to outside.
When I removed the cover off the JB that served as the "wiring centre"
the problem was plain to see. A chain dead ants in an arc between live
and earth.

That little lot did not seem to be upsetting anything RCD wise (not sure
how conductive spider silk is?), although the lens on the front of the
PIR had disintegrated, which meant it was doing strange stuff with the
lights.

(all my outdoor circuits are on their own CU anyway so that problems
like that don't get imported to the house side of things)

Looks like the remains of the chrysalis of some insect to me.

Silk was (and still is on a small scale) used for making insulators.
It has a very high breakdown voltage.

Like paper insulation, its role tends to be for support (spacing)
conductors, with something else (air or oil) also forming part of
the insulator.

Ah! that's where my wing mirror spider has got to.

Might be - there was certainly lots of silk there as well - I raked out
a fair bit before I decided to get a camera.

That would explain the lack of leakage problems then ;-)
