We just recently moved into our new place and found these bugs crawling into our living room from the patio door and molting They moved very slow and when i try to catch one, it jumped up about 12 to 18 inches straight up. I lived in Southern California and never seen an insect like this. Can you help me identify this insect, thank you.

Lawn Shrimp

Dear Jonathan,
Commonly called a Lawn Shrimp or House Hopper, this terrestrial Amphipod is not an insect, but a Crustacean.  Lawn Shrimp are native to Australia, but they have naturalized in Southern California because of the irrigated gardens that are so common.

A large number of these pinhead sized bugs hatched on my bonsai maple buds and leaves on a warm February week.

Maple Aphid, we believe

This is an Aphid, and based on our research and information contained on Influential Points and BugGuide, we suspect this is a Maple Aphid, Periphyllus testudinaceus, a species native to Europe. 

Thanks Daniel,
This is great information and very interesting.

Hello Bugman!
We found this bug in South Africa in Maize. But I have no idea what bug it could be. Maybe you can help me.
Tank you very much!!

Spotted Maize Beetle

Dear Simon,
We believe we have correctly identified your Beetle as a Spotted Maize Beetle thanks to the Beetles in the Bush site where it states:  “One of the most common insects encountered in agricultural fields in Argentina is
Asylus atromaculatus (spotted maize beetle).  This native species can also be found further north in Bolivia and Brazil, and as implied by its common name it is frequently encountered in maize fields.  The species, however, is also common on soybean, on which the individual in the above photo (and mating pair in the previous post) were found.  Looking like some strange cross between a checkered beetle (family Cleridae) and a blister beetle (family Meloidae), it is actually a member of the Melyridae (soft-wing flower beetles)—placed with the Cleridae in the superfamily Clerioidea.”  Elsewhere on Beetles in the Bush, it states:  “For all their ubiquity, however, their economic impact seems more nuisance than substantive. Corn breeders complain about interference during tasseling, and larval feeding on seeds during or just after germination seems to be on the rise due to increased use of conservation tillage, but overall this species seems to be more bark than bite.”  On the A Tale Unfolds site it states:  “Astylus atromaculatus is a species of beetle in the family Melyridae. It is variously known as the Spotted Maize Beetle, or Pollen Beetle. It is indigenous to Argentina and neighbouring countries, but has been accidentally imported into various other regions such as the warmer regions of North America and much of Africa, where it has become invasive.”  We also found a posting on iSpot.

Diaprepes Root Weevil

Dear Francis,
This is a Diaprepes Root Weevil,
Diaprepes abbreviatus, a species “Native to the Caribbean, adventive and established in so. US: so. & central FL (1964), so. TX (Cameron & Hidalgo Cos 2000, Corpus Christi 2005, Houston 2009; map), so. CA (2005), LA (2008); further north in greenhouses” according to BugGuide, which also notes “color highly variable (from gray to yellow to orange to black).”  The Diaprepes Root Weevil is a significant agricultural pest, and according to BugGuide:  “Major pest of citrus crops: larvae often girdle the taproot, which may kill the plant and provide an avenue for Phythophora infections. A single larva can kill young hosts while several larvae can cause serious decline of older, established hosts.”  According to Featured Creatures:  “Diaprepes abbreviatus has a wide host range, attacking about 270 different plants including citrus, sugarcane, vegetables, potatoes, strawberries, woody field-grown ornamentals, sweet potatoes, papaya, guava, mahogany, containerized ornamentals, and non-cultivated wild plants.”  Since it is the first of the month, we will be featuring your submission as the Bug of the Month for March, 2017.

I greatly appreciate your response and am honored that this photo will be the feature of the month! We’ll be sending more photos to share from Learning Gate Community School.

Good afternoon Bugman,
We have a very big problem with the insects in the below photos, and the problems keeps escalating very quickly. It is a very big concern, as they are busy taking over our whole yard and they leave their sticky residue on everything.
Can you please have a look at the photos and see if you know what this is, and if possible give me some instructions on how we can get rid of them?
The start out like the larvae on the left of the photo , and then become beetles like the one on the right of the photo.
In the bottom photo you can see a whole lot of them together in their various stages of development.

Multicolored Asian Lady Beetle Larva and Pupa

Dear Filna,
It is quite interesting to us that you are concerned about the larvae and pupae of these Lady Beetles, but you have not mentioned the winged adults.  We strongly suspect that these are the early stages of the invasive Multicolored Asian Lady Beetles,
Harmonia axyridis, but we had to verify their occurrence in South Africa on iSpot where we discovered the most awesome Clime Lab logo posted by who is “studying the thermal biology of the alien ladybird Harmonia axyridis (harlequin ladybird, multi-coloured Asian lady beetle) in South Africa and their observations will be useful for determining microclimates.”  The Multicolored Asian Lady Beetle is a threat to native Lady Beetle species in North America because the invasive species is so prolific, and it will prey on native species.  They get quite numerous and they frequently cause homemakers to fret when they enter homes to hibernate in great numbers as the weather begins to cool  Though we recognize the threat they make to native species, alas, What’s That Bug? does not provide extermination advice.

For a couple of months we have been assaulted by literally MILLIONS of little beetles that resemble lady bugs. They are literally everywhere…outside and inside! These come in a range of colors from deep red through mustard yellow. Some have black spots, some don’t. We live in the Piney Woods of East Texas. Any thoughts? Thank you!!! (Sorry the photo is a bit blurred.)

Multicolored Asian Lady Beetles

Dear Overwhelmed,
Though your image is quite blurry, we suspect you have encountered the introduced Multicolored Asian Lady Beetles that are known to hibernate indoors in great numbers.  See BugGuide for examples of the color and pattern diversity exhibited by the Multicolored Asian Lady Beetles,
Harmonia axyridis.  Our Better Nature has an interesting article on invasions of Multicolored Asian Lady Beetles.

Dear Daniel — Bull’s Eye!!!  That’s definitely what we’re dealing with!  I so appreciate your help. I’m engaging in the process of searching out and caulking every miniscule seam, crack or nail hole in my siding, though I expect it will not fully resolve this issue. I share the concern expressed in response to another inquiry re: the attack on our native lady beetles and the resultant decrease in genetic diversity. Let’s hear it for introduced species!  (A bit of sarcasm there). At any rate, thanks so much for your response!
