Multicolored Asian Lady Beetle Pupa

This is the pupa of a Lady Beetle (AKA Ladybug) and normally that would be a good thing as they are important predators that help to control Aphids.  This however is the Pupa of an Invasive Exotic, Multicolored Asian Lady Beetle, a species that is most likely displacing native species as it is so aggressive.  Here is a BugGuide image.   Larvae will prey on other Lady Beetle larvae.  Multicolored Asian Lady Beetles are reported to invade homes in large numbers to hibernate.

A Facebook Comment from Kiki Gee:
The Asian lady beetle has decimated our indigenous 9 spotted lady beetle. If you ever find one dead or alive, Dr. John Losey at Cornell University would like to know. I worked with him, and he has an ongoing study trying to increase their population.

Aloha from Hawaii. I live in mililani on oahu and found this really neat guy on my trash can. He is about half an inch long and really strong. I had a really hard time removing him from the trash can and transferring him to a tree. I have lived here 25 years and never seen this insect before. Please can you identify him. I thought he might be a longihorn type of beetle.
Much mahalo!

Longicorn

Dear Jenz,
Like so many creatures found in Hawaii in the 21st Century, this Longicorn is probably an introduced species.  We believe we have correctly identified it as
Coptops aedificator thanks to Cerambycoidea which lists the range as “Arabia, Africa, S. Helena, S. Thomé, Cabo Verde, Madagascar, Comores, Seychelles, Mauritius, Ceylon, India, Andaman. Introduced in China (Taiwan) and Hawaii.”  It is also pictured on Forestry Images where it is identified as the Albizia Long-Horned Beetle, and iSpot.

Longicorn

Mahalo for taking time out of your day to identify him.  We also have Madagascar stick bugs here.  We live on the rim of a nature reserve and find many different insects here. There may be more pics in the future. Aloha jenz

this bug/worm/fuzzy looking thing is all over and around my rose of Sharon bushes, but I can’t tell if it is eating what also appears to be tons of tiny aphids, but they are just small lines vs. round – all over the leaves….not sure if those of the larvae of this, or this is eating those….this bug is less than 3/4″ long and soft bodied vs. beetle-like.

Multicolored Asian Lady Beetle Larva

This is the larva of a Lady Beetle and it is likely feeding on the Aphids that have infested your Rose of Sharon.  Based on this BugGuide image, we are quite confident that this is the larva of the Multicolored Asian Lady Beetle, Harmonia axyridis, an invasive species that is likely contributing to reduced populations of native Lady Beetles.

Thanks so much. I do not use chemical pesticides or herbicides, but is there anything natural I should/could do to rebalance?

Female Flower Chafer

Dear Jason,
The best we are able to provide at this time is a genus identification.  This is a female Flower Chafer in the genus
Valgus, which we verified by matching your image to this BugGuide image.  According to BugGuide:  “Small compact-shaped (almost tick-like) scarabs that visit flowers. Note short elytra, leaving much of abdomen exposed.”  BugGuide also notes that the habitat is “decomposing wood, usually associated with termites; adults visit flowers” and “Larvae are wood decomposers, usually associated with termite colonies.”  The more research we did, the more confident we are that your individual is a female of an adventive species introduced to North America from the Old World, Valgus hemipterus.  According to the Generic Guide to New World Scarab Beetles:  “Distribution: Palaearctic (Algeria, Europe, Iran, Morocco, southern Sibera and Tunisia) and Nearctic:CANADA: Ontario. USA: Michigan, Ohio.”  The same site also states:  “Adult females are attracted to moist, rotting wood to oviposit, although oviposition has been observed in fairly dry wood and in living trees. Females leave colonized wood to seek out new oviposition sites in early summer and use their pygidial spines to create such sites. The entire life cycle of Valgus hemipterus can be completed within a log, and Nearctic specimens have been taken from rotting wood of the American elm (Ulmus americana L.). Oak, birch, elm, and chestnut are common host trees in Europe.”

A little help if you please! My family enjoys looking up in wildlife guides, the bugs we find outside (and inside) our suburban home in Illinois. The closest thing we come up with for these two is the “spotted tiger beetle.” But these little guys are not spotted as the description/images/name would have us believe. Are they an undeveloped youngster version of this beetle perhaps? Or are we barking up the wrong bug? We’ve been able to identify all the other local insects thus far but are very unsure on this one. Thank you for taking the time to look! It’s kinda buggin’ me.

Green Immigrant Leaf Weevils

Dear Benjy,
Tiger Beetles are fast moving predators, and they are nowhere near as docile as these invasive Green Immigrant Leaf Weevils.  According to BugGuide:  “native to Europe (widespread there), adventive in NA, established in the northeast (NS-*SK to *PA-IL) + *UT & BC” and they feed on “primarily Yellow Birch (
Betula alleghaniensis).”
