Lady Beetle Larva

Lady Beetle Larva

Hi Joyce,
In recent weeks, we have had countless requests for the identification of Lady Beetle Larvae, the immature form of Ladybugs, but since out computer was so slow, we did not post any, nor could we take the time to respond personally.  Our fast new computer is allowing us to address ever so many more identification requests.  The larvae of the Lady Beetle is not poisonous.  They are predators of plant feeding insects like aphids, and we have gotten reports of people being bitten by larval Lady Beetles, but the bite is just a harmless nip.

    This is larva of invasive Harmonia axyridis. Of course, it IS poisonous. For ants and other small creatures. Try to put it on you tongue, close your mouth but do not chew. You will feel the bitter taste of alkaloids.

    I have been bitten x 2 by this larva! The bite is painful and close to a bee sting but doesn’t last as long. It leaves a pretty big bright red sore and takes a couple of weeks to heal. They are vicious!

    I live in Northern CA

    Lady Beetle larvae is much like the native species found through the United States. They are small, hemispherical in shape, and can be found with and without spots. Their colors may vary from black, and orange to a dull cream. However, unlike the native species, this lady beetle larvae can be quite aggressive. Masses of lady beetle larvae have been known to swarm and even bite when seeking shelter for the winter months. In this regard, they have been an unwelcome guest for homeowners that don’t find them to be good luck at all, but rather a nuisance.

    I was bitten by a tiny one today on my hand ( about the size of a sesame seed). I definetly noticed! Wouldn’t want a bigger one to bite. It stung, but didn’t leave a mark. Not going to lie, I smushed it! It was tiny, but creepy and it was biting me.
