Marros, Carmarthenshire.
The most colourful specimen of this species I have encountered, initially thought to be C. molliculana. Dissection has shown it to be C. atricapitana (female).

Just a normal IR sensor, like on any TV or stereo, but this one has a special 360 degree lens on it so it can see IR from any direction.
The Roomba uses its IR sensors for several purposes: detecting its charging base, "seeing" virtual walls, and listening to commands on the remote control.
Photos from a recent session spent dissecting lionfish. These lionfish were brought in by local Bahamian fishermen for CEI's "You Slay We Pay" campaign.
The drive motor is not just a simple DC motor. That's part of it, and what the red & yellow wires are for. But the other wire bundle (black,white,brown,blue) goes to the odometer sensor, measuring in mm/sec how fast the wheel is moving.
My favorite scissors dissection problem is this one.
From a square S=ABCD with center M and vertices labelled clockwise from its northwest corner, cut out the triangle T = CDM.
Next, reattach T to what was the original square by rotating it ninety degrees clockwise about C until DC coincides with BC.
Here's picture of the resulting 6 sided figure. Call it H

Let's say we want to cut H into two pieces that can be reassembled to form a new square congruent to S.
Of course, one way to do that is to simply return the triangle we cut out back to where it came from.
The puzzle is to find a different solution.
