Hey Mr Bugman, what’s my bug?

Beach Hopper

BeachHopper

Hi Griffin,
This is a Marine Amphipod commonly called a BeachHopper, probably
Megalorchestia californiana.  Your submission will post live to our site later in June while we are away from the office.

Thanks for getting back to us.  We found this guy on the beach and he was resourceful, so we really wanted to know what he was.
Thank you!

Subject: Bright Orange Woodlouse

during my searches for various bugs and critters I’ve come across a total of three of these bright orange woodlice. I have a large plastic tub full of woodlice that I feed and observe, so the three I’ve found are part of my little ecosystem now.
what I’m wondering is, is this a rare genetic coloration of some sort? or a different species of woodlouse than the gray ones? perhaps neither and it’s something else, so I thought I’d ask you!

Orange Woodlouse

Orange Woodlouse

Dear Stolz,
Long ago we fielded a question about a Blue Sowbug and we learned it was infected with an Iridovirus which caused the coloration.  We found a similar question posted to BugGuide, but there is no response other than that it is identified as the European Sowbug,
Oniscus asellus.  On the Woodlice Oddities Page, it states:  “Orange Porcellio scaber This orange form appears to be rare in this region. The example here is the only one found in a collection of over 400 from the same compost heap – it is also the only one, of two, that I have observed over the last 10 years. The red forms of woodlice are genetically determined but their rarity suggests that this form is not as well adapted to the habitat as the darker gray forms.”  On Terrain.net it states:  “The Orange woodlice is a rare colour form the the common slater  Porcellio scaber.”  On BugGuide we learned that Porcellio scaber is a synonym for Oniscus granulatus.

Subject: freshwater aquarium isopod?
Location: Australia

Hi, I found this bug in my tank after adding some new plants. I think it might be an isopod of sorts but am unsure as to what type it is. I have it currently in a cup of water with some moss and the small mystery snail that also came with the plants. I’m too worried to keep it in the tank in case it is a parasitic bug that could harm my fish. If the bug is completely harmless please let me know so that I can add it back int the tank instead of them being stuck in a small cup. If it helps, I have noticed that it tends to roll into a ball when it feels threatened. Thanks.

Dear weilmanu,
We agree that this is some aquatic Isopod and we cannot guarantee that it will not cause problems in your aquarium.  We would not recommend introducing it to your aquarium.

We woke up today with a bunch of small brown bugs with pincars. Just by back door outside all dead. Can you let me know if they are something we should be concerned about?

Lawn Shrimp

Lawn Shrimp

Dear Liz,
The presence of Lawn Shrimp,
Arcitalitrus sylvaticus, in the landscaping generally goes unnoticed until we have a good rain that soaks the ground, at which time they often emerge in alarming numbers, dying on the concrete or entering homes to die.  Lawn Shrimp are native to Australia and they are also known as House Hoppers.  See BugGuide for additional information on Lawn Shrimp.

Woodlouse

Woodlouse

Hi Jesse,
This is a Woodlouse or Sowbug, a type of terrestrial Isopod.  Though they often enter homes, they are considered benign and they will not damage your house or its belongings, unless rotting organic matter is valuable to you because that is what they eat.

I have an infestation in a mature (about 50ft high) Camphor tree. The infestation seems to be around the root and the insects (in the picture) are revealed if I pull some bark out. Any help identifying the insects would be appreciated, thanks.

Woodlice

Woodlice

Dear Anshuman,
These are Woodlice, a type of terrestrial isopod.  They are commonly found in cool, dark, damp places within the garden where they feed on dead plant material.  If the base of the tree is rotting, they may be feeding on the rotting wood, but they will not harm living portions of your camphor tree.  Woodlice will also enter homes, and they are most frequently found in basements where the conditions are favorable.
