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.”

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.

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.

Your letter to the bugman:  Hi  we came across this guy the other day. Found by my grand daughter. Just wondered if you have seen anything like it before. Thanks

Mealybug Destroyer Larva

Dear Gary,
This looks to us like the larva of a Lady Beetle known as a Mealybug Destroyer, a species native to Australia that has been exported for agricultural purposes to help control populations of Mealybugs in agricultural areas.  The larva is pictured on the Brisbane Insect site.

I’ve tried to find side-by-side comparisons of the native ladybugs and Asian ladybugs without success. Can you tell me which this one is?  I suspect it is Asian. I have several around my garden, some still in larval form and others pupating. Also, we are having a mild November, but do you know if these will overwinter with me? Thanks a lot!

Multicolored Asian Lady Beetle Larva

Dear C. Hall,
In our opinion, this looks like a Multicolored Asian Lady Beetle larva.  This species has larger and often more aggressive larvae that out compete, and even feed upon the larvae of native Lady Beetles, which may eventually lead to displacement of native species.

Aloha – On a milkweed plant, nurtured for the Monarch caterpillars use, I found this pair of lady beetles planning the next generation. Yes, there were yellow aphids on the plant which I’ve seen one of the lady beetles near. Thanks for all the informative posts.

Mating Seven Spotted Lady Beetles

Dear Eliza,
We identified this amorous pair as Seven Spotted Lady Beetles,
Coccinella septempunctata, thanks to an online article published by the University of Hawaii entitled “Not All Lady Beetles are Created Equal:  Learn about different Types of Lady Beetles in Hawaii with Special Talent“.  Alas, we cannot currently access BugGuide where this species is represented because we would like to verify its native range since so many species currently found on Hawaii have been introduced.  According to Arkive, the Seven Spotted Lady Beetle might be native to Europe.  Arkive states:  “Ladybirds are perhaps the most well-known and popular of all British beetles, and the seven-spot ladybird is one of the commonest species. This rounded beetle has bright red wing cases with 7 black spots, although some individuals may have more or fewer spots. The thorax is black with patches of pale yellow at the front corners. The common name of this group of beetles, ‘ladybird’, was originally given to the seven-spot in honour of the Virgin Mary; the red wing cases symbolising the Virgin’s red cloak, with the seven spots representing her seven joys and seven sorrows.”  Our previous research on the Seven Spotted Lady Beetle indicates “According to BugGuide:  ‘It has been repeatedly introduced in the US from Europe, to control aphids.  This widespread palearctic species was intentionally introduced into N. America several times from 1956 to 1971 for biological control of aphids. All of those attempts apparently failed in getting C. septempunctata established, but in 1973 an established population was found in Bergen Co., New Jersey. This population is thought to have been the result of an accidental introduction rather than a purposeful one (Angalet and Jacques, 1975). Since 1973, this species has spread naturally and been colonized and established in Delaware, Georgia, and Oklahoma. (Gordon 1985) It has since spread throughout N. Amer.'”

Mahalo for you extensive paragraph on the 7 spotted Lady Beetles in Bug Love. Yes, many hitchhiking bugs now make Hawaii home. The Madagascar gold dust day gecko has appeared in my carport over the past week. Eeeek!
Sending the attached 23 sec vid for your review of the wiggling male. I was rather surprised to see his action, since most bug mating is static.
