Early morning in a wood straddling Hampshire and Wiltshire. The air is dry, the sun smiling, the audience fidgeting with anticipation. All crave sight of an enormous underwing, resplendent in chestnut and ivory. An underwing belonging to His Imperial Majesty the purple emperor. One of Britain's biggest butterflies takes to the wing with glides of breathtaking power, then swoops elegantly to the ground. And promptly undermines its stateliness by feasting on fresh canine faeces. Such is the paradox of the purple empire.
Now is the peak season. Arrive early: although emperors rarely stretch wings until the air is warm, their feeding forays usually cease by 10am, when they return to canopy concealment. This cues your move from Bentley's eastern car park to enjoy the rest of the wood's winged bonanza.
White admirals – a mini-emperor in looks – proliferate. Small pearl-bordered fritillaries favour damp parts of the eastern clearing. Purple hairstreaks favour oaks and brambles. Whiteletter hairstreaks need more tracking: try around the Ralph Whitlock memorial.
Around lunchtime, relocate south-west to the nearest fringes of the New Forest. Visit Ogdens, one of the national park's least-disturbed sites and stroll eastwards along Latchmore Brook for a dragonfly treat. Beautiful demoiselles bounce above streamside vegetation like iridescent yo-yos. Golden-ringed dragonflies patrol.
Start the following day on the north border of Wilverley Inclosure. Walking eastwards, search pathside bracken for two rare flowers. The sublime lesser butterfly-orchid can be abundant, but you will need luck to find wild gladiolus which, in Britain, occurs only in the New Forest.
As the day warms, have another stab at yesterday's star dragonflies. From Puttles Bridge car park, walk south along Silver Stream or north-west along Ober Water. The former is particularly good for southern damselfly. Ober Water can be great for scarce blue-tailed damselfly, white-legged damselfly and small red damselfly.
Finish the weekend by wandering amid heathland at Pig Bush near Beaulieu Road railway station. There's a good chance to see adder (but smooth snake or sand lizard only for the amazingly lucky). And a fabulous suite of plants occurs along the ridge leading south-west to the railway line.
