Presumably ovipositing, otherwise I don't understand the curious dance this colourful fly was doing. Quite the display given its wing and body colours and patterns.

Ichneumonid wasp ovipositing inside an aphid.

Low-light conditions, a bit blurred. Was fascinating to see, as it iterated over multiple target apids and stabbed them all. Aphids didn't even attempt to run. Interestingly, only chose small aphids, even a very small one (seen in this photo at the lower left, near the posterior tip of the wing of the wasp).

Yesterday would have been the 80th Anniversary of D-Day, but oceanographers and our ability to make predictions called for a one-day delay. This ensured that the landings were a success. #WorldWarTwo

In what calculator does

0.004 * 25 = 0.096

???

Clearly a calculator to be retired from the market.

Why a student would need a calculator for that, and not realise the inaccuracy of the outcome, is quite another matter.
