We dug a pond in August 2020 with a small rockery and logpile with lots of hide holes and it had its first frog sitting in it within 12 hours, nearly two years on it honestly looks like it's been there for ages. At the moment there are damselflies, hoverflies (including the little hummingbird ones), bees, pondskaters, a variety of fly species and the odd wasp flitting around the surface. We've had dragonflies, stoneflies and mayflies out there too. Also water spiders, jumping spiders, tadpoles, isopods, two species of pondsnail (one bought on purpose, one presumably came in on plants), and water beetles.
We don't mow the front garden more than three times a year, I plant things that will keep a long flowering period so that early and late pollinators have food available (lots of cyclamen, daffodils, knapweed, elder, wild and cultivated geraniums, buddleia, mock orange, honeysuckle, abelia, lavender, early and late roses, cat mint, lemon balm, pinks, verbena bonariensis, valerian, late flowering fuchsias, and we don't remove dandelions or mow the back garden early in the year). We don't use pesticides, tolerate a few weeds (bramble on one fence and jack-in-the-hedge in bits of the back garden), have a hedge instead of a wall or fence at the front, and i don't prune plants as soon as they go over - we have long-tailed tits, goldfinches, dunnock, blackbirds and greenfinch in the garden in the winter looking for seeds and berries among all the dead flower heads on things like the knapweed and lemon balm.
