Spotted this hoverfly in my room a few days ago. Not sure what species it is. Can anyone identify it?

Its been a while since I had the Macro Lens on but a few minutes in the garden and here’s the result.
Hoverflies, sometimes called flower flies or syrphid flies, make up the insect family Syrphidae.

Paragus yerburiensis, Family: Syrphidae

Flies that visit or hover on flowers are not all referable to flower flies or hover flies, but those that do it usually by hovering for some time with a shrill hum are regarded flower flies or hover flies or Syrphidae. The family includes small to rather large (3-18 mm), bristle less, brightly coloured flies, may be striped, banded or spotted yellow on a blue, black or metallic ground colour. Head variable, usually as broad as or a little broader than the thorax, thorax rather large and robust, moderately arched, rarely with bristles, abdomen variable in shape, composed of five or six visible segments, rarely four, wings comparatively large.
Syrphidae draw attention mainly because of their ecological services. These tiny flies, take a crucial role in pollination and serves as an important pollinator of many flowers. Syrphid flies are frequent flower visitors to a wide range of wild plants as well as agricultural crops and are often considered the second most important group of pollinators after wild bees. The Syrphidae are also acts as biological control agents. Larvae of many Syrphidae prey upon pest insects which includes such leafhoppers, aphids and coccids. So, they are seen to control the pest level in such agricultural fields.

The Syrphinae constitute one of the three subfamilies of the fly family Syrphidae. Most larvae of this subfamily feed on aphids. Each larva can consume up to 400 aphids during development. When syrphid larvae are abundant, they may reduce aphid populations by 70 to 100%.
The tribe Paragini, with the single genus Paragus, is a compact and distinctive group occurring in all continents other than South America and Antarctica. More than 142 species and subspecies of Paragus have been described. Paragus species are small, slender to moderately robust, with thorax black or with apex of scutellum pale, and abdomen usually extensively red-orange to entirely black.
Paragus yerburiensis is aphidophagous (aphid-feeding) syrphid that predates Aphis craccivora
Flies in the family Syrphidae are commonly known as hoverflies, flower flies, or syrphid flies.
As their common names suggest, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects.

A hoverfly (Syrphus sp.), likely Syrphus ribesii, perched on a serrated stinging nettle leaf (Urtica dioica) in a garden in Limerick, Ireland. The yellow and black banded abdomen, large compound eyes, transparent veined wings and yellow thorax are all beautifully sharp. A classic example of Batesian mimicry — this harmless fly mimics the warning colours of wasps and bees to deter predators.

The first Eumerus hoverfly I have noticed in our garden, although they have probably been there all the time.
