I-SPY Wildlife - A 6 a Day Challenge

Insect - oil beetle (so google lens tells me)  he was about 4.5cm long

I'd never heard of an Oil beetle before and now, they're had a mention on a FB page for Pembrokeshire Coast (West Wales). 

These fascinating insects have one of the most unusual lifecycles around. When their eggs hatch, the tiny larvae climb onto flowers and wait for a passing bee. Hitching a ride back to the bee’s nest, they settle in, feeding on the bee’s food stores (and sometimes even its eggs!) before growing into adults and starting the cycle all over again.
Oil beetles rely on healthy bee populations and bees need plenty of native wildflowers to thrive.
That’s why Pembrokeshire’s species-rich coastal grasslands and heaths are so important. With the right management to stop scrub taking over, these habitats can support a whole network of wildlife.
We’re lucky to have three species of oil beetle here in Pembrokeshire, including the nationally rare Short-necked Oil Beetle.
