Wasps and yellow jackets will chase you when they feel their nests are in danger. They step up their defense and will do anything necessary to remove the threat from the vicinity of the nest or to escape – including stinging you. Yellow jackets will instinctively chase you if you're near their nest.
The main difference is invisible to the lay observer, given that most encounters happen when the wasp or fly is airborne: wasps have four wings, hoverflies two. More obviously, wasps are "wasp- waisted" while the hoverfly's thorax and abdomen are divided by less of a narrowed section or have none at all.
Fairyflies are very tiny insects, like most chalcid wasps, mostly ranging from 0.5 to 1.0 mm (0.020 to 0.039 in) long. They include the world's smallest known insect, with a body length of only 0.139 mm (0.0055 in), and the smallest known flying insect, only 0.15 mm (0.0059 in) long.
The panic that a swarm of hoverflies can generate belies the fact that they are immensely beneficial insects. Many of their larvae (the baby hoverflies that look like maggots) crawl around on plants feeding on the aphids that would otherwise eat our flowers and crops.
One of three very similar yellow and black banded species. Produces the loud hum often heard in midsummer woods. Also seen in gardens and fields.
Apply a cold compress to the site of the sting to dull pain and reduce swelling. If stung on your arm or leg, elevate it to reduce swelling. Take or apply over-the-counter medications like antihistamines or corticoid steroids to reduce symptoms near the sting. Consider taking acetaminophen to manage pain if needed.
Marmalade hoverflies are one of the smallest (0.9 – 1.2cm), yet most commonly seen hoverflies in the UK. With black and orange stripes, the adults resemble wasps, but they do not sting.
Hoverflies also produce defence buzzes, and it has been suggested that they represent either a general alarm signal or acoustic mimicry with bees (Rashed et al., 2009; Moore & Hassall, 2016).
How to Get Rid of Hoverflies
- 1 – Use a Fan. If the hoverflies are on your patio and you have an outlet, you can use a fan.
- 2 – Make a Fly Repellent. Another option is to make a fly repellent.
- 3 – Use a Fly Trap.
- 4 – Provide Plants with Nectar and Pollen.
Adult horse flies grow to between ½ and 1 ¼ inches in length. Their stout bodies are gray to black in color and their wings may be clear or slightly cloudy. Horse flies have large, bright green or purple eyes and very short antennae.
Many bee species hover at least momentarily, and especially, this behaviour can be spotted as they approach flowers. However, some bee species engage in hovering behaviour more than others. On many occasions, I have witnessed bumble bees hovering for a second or two around flowers.
Hornets, like wasps, have six legs and two pairs of wings.
Yellow jackets are commonly mistaken for bees because of their striped black-and-yellow markings. The major difference is that yellow jackets are smooth—never fuzzy or hairy like bees—and their yellow stripes tend to be brighter and shinier. They also have a thin, “wasp†waist.
Hover flies tend to build their nests in trees or other appealing spots in the garden.
Hoverflies are excellent examples of Batesian mimicry (named after H W Bates who first described it in 1862). They generally mimic bees and wasps – insects that sting and also taste unpleasant, so are avoided by predators.
common name: a hover fly. scientific name: Allograpta obliqua (Say) (Insecta: Diptera: Syrphidae)
Carpenter Bees are those big, fuzzy bees flying around your house. Several of them may hover in one spot, and they seem to be guarding something. They'll chase you, harass you, annoy you, and you're probably worried they'll swoop in and attack you every time you pass.
Management is usually not necessary and hover flies are beneficial insects They are considered the second most important pollinator next to bees (Figure 2). Further, some species of hover flies can control garden pests such as soft-bodied aphids and scale insects.
Hornets eat leaves and tree sap but are also accomplished predators, feeding on flies, bees, and other insects.
