What Eats a Ladybug?

Ladybugs are beautiful insects to have around our gardens. Not only do they keep pesky insects at bay, they help our plants flourish by eating away at harmful aphids that would otherwise spread disease and disrupt growth.

An interesting fact about them is their immunity to their own toxins! They will eat anything soft enough and of suitable size.

Their legs can produce a foul-smelling fluid to discourage predators. Their bodies also bleed as part of a defense mechanism known as reflex bleeding.


There are various creatures that predate upon ladybugs, such as ants, birds, spiders, mites and even some carnivorous plants like Venus Flytraps.

Though it may appear cruel, certain predators actually have good reasons for devouring ladybugs. Over time they may have developed immunity to the toxic substances released by ladybugs through natural selection or just evolution allowing them to better cope with these chemicals.

Ladybugs can produce an unpleasant odor that dissuades predators from devouring them, and also boast special organs in their feet which detect what they touch – this helps them navigate back home after foraging; this is known as chemoreception.

If a ladybug finds its way into your home, it could be searching for warm places to overwinter. While some may attempt to move it elsewhere, sealing any cracks or crevices that provide entryways might be more effective in keeping out these unwanted visitors.

Homeowners often struggle to prevent ladybugs from overwintering indoors. To do so, it is best to maintain an environment as warm as possible, without painting or decorations which might deter their presence.

Another effective strategy for keeping ladybugs away is providing them with access to water. Fill a bowl or container with pebbles, adding enough liquid so the ladybugs can reach them when landing, giving them somewhere safe from home-borne toxins where they can drink from this bowl of liquid.

Whenever a bird consumes a Ladybug, they quickly learn that this brightly-colored insect tastes disgusting – thus sparing hundreds of future Ladybugs from becoming dinner for that bird! This is the advantage of aposematic coloring.


Ladybugs are wonderful beneficial insects that help our gardens by eating away at aphids that wreak havoc, yet these beneficial insects have their own predators – mites! Mites from Mycetophagidae or Fungus beetles feed off the larval stage of ladybugs which in turn helps their populations remain balanced by taking advantage of any surplus aphids which might otherwise feed off these larvae and keeping their population balanced.

Ladybugs use their bright colors as a signal to predators that they are potentially toxic if eaten, known as aposematic coloring. Furthermore, when startled or startled accidentally they release foul-smelling fluid from their knee joints which stains and irritates predators which causes them to reject or discard it immediately rather than swallowing. This process of color signaling is known as aposematic coloring.

While Ladybugs may seem bothersome when crawling around our homes, these tiny insects pose no health threats for people or animals alike. Their bright color and unpleasant odor may attract pollinators like bees to your garden or yard!

One of the most frequently asked questions we receive about ladybugs and spiders is whether or not they eat each other. While ladybugs will occasionally feed on spiders, their appetite depends heavily on their environment and what other prey items there may be such as aphids and other insects; spiders generally do not rank high among these preferred prey items.

Adult birds find it challenging to teach their young not to eat Ladybugs. Therefore, young birds may give her a taste and learn that she tastes bad quickly before the Ladybug becomes too sick and stops being eaten as food.

However, some species of ladybugs carry bacteria that inhibits male offspring from developing into full grown females – something seen most notably with Seven-Spotted Ladybugs (Coccinella septempunctata), commonly found in North America and Europe respectively. While invasive Seven-Spotted Ladybugs thrive here due to our climate, their European native counterparts have become scarce due to a disease known as two-spotted Leafroller Disease; believed to have originated with Asian Lady Beetles (Harlequin Ladybugs).


As a general rule, ladybugs are seldom eaten by insects and spiders unless they’re desperate for sustenance. Their bright colors – which often feature orange and red with black spots – serve as a warning signal that these bugs taste bad; their powerful mouth parts also serve to dissuade any potential attackers from approaching.

Ladybugs play an essential role in maintaining natural ecosystems by eating both aphids and mites that cross their paths, helping keep numbers of prey species under control and thus maintaining ecological equilibrium.

As soon as it begins to get colder, convergent lady beetles will come together by the thousands in warm spots to overwinter. When spring comes around they emerge from hibernation and start mating; females laying several batches of eggs which they deposit on aphid colonies or food sources to lay more. Soon enough these tiny eggs hatch into larvae which then feed upon these food sources until adulthood arrives and they become adults themselves.

Adult ladybugs cannibalize themselves to survive; eating their own larvae and pupa as necessary is part of what makes ladybugs beneficial insects. Their exact rate of cannibalism will depend on climate and season; more likely they’ll go for the aphid population than any other food source; their consumption helps control it as a result, leading them to be considered beneficial bugs overall.

Flies are another common ladybug predators. Attracted by their smell, flies can capture these insects by seizing hold of them by their wings if they get too close. Some species can even inject nematocide directly into the body of ladybugs that releases a poisonous chemical that makes the insect taste unpleasant or toxic to other predators.

Other predators of ladybugs include larger spiders, wasps, dragonflies, frogs, toads, assassin bugs and stink bugs; larger mammals like bears may also consume these bugs when given the chance.


Ladybugs can be threatened by larger spiders, wasps, birds and mammals. Additionally they face competition for food from invasive Asian lady beetles often seen in gardens that compete for sustenance with native ladybug species. Ladybugs may also be eaten by parasitic wasps that inject their parasitic eggs during mating; or by fungal pathogens like Hesperomyces virescens which attacks its soft body.

Ladybugs use their bright coloration to warn predators that they taste unpleasant, which often serves to deter most threats. But persistent predators could still find ways around this defense if they continue hunting the bug – for instance larger spiders, beetles, frogs, toads, assassin bugs stink bugs large birds and mammals such as bears will all consume Ladybugs!

Ladybugs often mate and lay their eggs collectively in nature, where their larvae live together for several years before pupating into adults. When ready, pupae will form cocoons on plant stems or leaves before emerging as adults; once adult females emerge they swarm together for reproduction purposes and may even overwinter together as one large group if necessary.

Oblivious to their garden intrusions, ladybugs can actually be welcomed because of their appetite for eating away at aphids and other pests that damage plants – just one ladybug can consume up to 5,000 aphids during its lifetime!

Ladybugs feed on an assortment of insects and insect eggs, from Colorado potato beetles and European corn borer eggs to those belonging to other ladybugs! In fact, they may even eat the eggs of other ladybugs they come across while out and about!

Ladybugs do not carry diseases that affect humans or livestock, are non-toxic to pets or livestock, and rarely bite humans (though pinching may occur if threatened or hungry). Their bites do not cause serious injuries but may be uncomfortable. Furthermore, their stress or pain caused foul-smelling odors which may be disturbing for some individuals.
