Fifteen Spotted Lady Beetle

Dear Dawn,
We are quite confident we have correctly identified your Fifteen Spotted Lady Beetle,
Anatis labiculata, thanks to this BugGuide image.  According to BugGuide:  “Like other Anatis species, Fifteen-spotted Lady Beetles darken with age. In the oldest individuals, the spots may not be visible against the dark background color.”

Fungus Eating Lady Beetle

Dear Lyndie,
This is a very interesting submission for us.  We quickly identified your Fungus Eating Lady Beetles,
Illeis galbula, on the Brisbane Insect website where it states:  “Both adults and larvae feed on fungus and black mold on leaves” and “The Fungus-eating Ladybird larvae grow up to 8-10mm.  They are creamy white in colour with lines of black dots on their back. They are usually found feeding those black mold or fungus on leaves. The larvae runs very fast when disturbed.  Larvae feed only on powdery mildew type of  fungus (Oidium sp., Erysiphales) which infecting various plants. ”  Most Lady Beetles are considered beneficial as they are predators, but we have never heard of a beneficial Lady Beetle eating detrimental fungus on plants.  We decided to find another source for information, so we found the New Zealand Arthropod Collection Fact Sheet Series where it states:  “This adventive ladybird was first found in New Zealand in 1985 in Auckland. It comes from Eastern Australia and is also found in New Guinea. It is now present in New Zealand’s North Island, where it occurs in gardens, parks, and other areas where powdery mildew fungi infested plants occur. It is most commonly seen on cucurbits (Curcurbaceae).”  The site also states:  “The adult and larval ladybirds eat powdery mildew fungi and are probably attracted to the smell of powdery mildew. This kind of fungus forms white growths on the surface of leaves that include its fruiting bodies (spores). In spring the over-wintering adults may feed on pollen. The adults and larvae of many fungal feeding ladybirds have modified mouth parts for scraping fungal hyphae and spores from the surface of leaves.”

Your letter to the bugman:  Discovered a Two-Toned Asian ladybird beetle by my porch  light the other night. Believe that’s the proper ID, one mentioned on a similar photo that its possible that its its wing-case died, leaving one to be lack of red pigmentation?
Curiously, the other post was taken years ago at Disney World, so could this be possible that its genetic mutation instead?

Two-Toned Multicolored Asian Lady Beetle

Dear Alexis,
Sorry for the delay.  We were interrupted while creating a posting for your submission and it was saved as a draft and forgotten.  The Multicolored Asian Lady Beetle is quite variable.  The suspicion about the dead elytra or wing cover is interesting, but we don’t know if it is accurate.

Your letter to the bugman:  My daughter found this bug on the beach at Grand Traverse Bay and we couldn’t find any similarly spotted bug online. Can someone tell us the name of it?

Eye-Spotted Lady Beetle

Dear David,
We quickly identified this Eye-Spotted Lady Beetle,
Anatis mali, thanks to this BugGuide image.  It has been 11 years since we have posted this species to our site.  According to BugGuide:  “Arboreal where aphids are found.”  We always love posting images of native species of Lady Beetles whose numbers are on the decline, due in part to the introduction of the Asian Multicolored Lady Beetles.

Your letter to the bugman:  I’ve lost my squash crops due to these fellows, which I didn’t realize were harmful at first. I’ve pulled out the squash, but now I’ve found one on my cherry tomato plant (the plant has gotten quite big and is in very close proximity to where the squash were). I thought at first that they were squash beetles, but now I’m pretty sure they’re Mexican bean beetles, and I don’t want to lose my tomatoes.

Squash Lady Beetle Larva

Dear Andrea,
After you commented on a posting to our site of a Squash Lady Beetle larva indicating you thought it was misidentified, you stated you were certain your identification of a Mexican Bean Beetle was correct since you also had images of the adult.  Your adult image lack critical sharpness, however the size of the spots causes us to believe that you too are being troubled by Squash Lady Beetles,
Epilachna borealis, based on images posted to BugGuide where it states that the Mexican Bean Beetle “E. varivestis has smaller markings and two spots in the third row of elytral markings, not one.”  According to Insect Identification:  “Squash Lady Beetles feed on the leaves of plants in the squash family. This includes summer squash, zucchini, cucumbers. They also eat bean and pea plants, making them a nuisance in the garden. They are easy to identify if you are already familiar with the dome-like shape of other Lady Beetles. Squash Lady Beetles are yellow with black spots on both the elytra (wing covering) and the thorax. They are slightly larger than other, beneficial Lady Beetles. They may be mistaken for Spotted Cucumber Beetles because of the similar color and spots. (The body shape is different though: the Spotted Cucumber Beetle has a long, flat body.)”  There are additional images and information on MOBugsWalter Reeves notes:  “Note that there is a similar insect called the Mexican bean beetle. This insect has 8 spots on each wing cover rather than the 7 you see here.”

Squash Lady Beetle

Okay, thank you. I found a better picture (which you can use on the site if you’d like). I’ve attached it. You may need to zoom in, but it is more clear. Thanks again.
Best,
Andrea

Late in the afternoon, after work, Daniel decided to do some weeding in the garden.  The annual wildflowers, including fiesta flowers, lupines and California poppies are blooming and other wildflower seeds are sprouted.  Around dusk (slow shutter speed resulted in blurry image), Daniel noticed what he believes are Convergent Lady Beetles mating.  It is very exciting to see a native Lady Beetle in the garden as opposed to the invasive Multicolored Asian Lady Beetles that are displacing native species in many places in North America.  The Natural History of Orange County has some excellent images of Convergent Lady Beetles, and BugGuide states they feed on:  “Aphids, also whiteflies and other soft bodied insects.”

Mating Convergent Lady Beetles

We got trolled on Facebook by Toni Merida:  How can anyone who knows that much about gardening not know what a ladybug is?

The answer to Toni’s question is that while our editorial staff knew that these were Lady Beetles, we were uncertain of the species and we wanted to substantiate the species since we tend to see invasive Multicolored Asian Lady Beetles in our garden, and that larger, more aggressive species is contributing to the decline of many native species of Lady Beetles.
