Dear Bugman, I’ve been finding these buggers in the machine that I use to sanitize my baby’s bottles. After the steaming cycle is done, I wipe down the excess water, and I leave the cover ajar for all the water to dry, I would often find one or so of these hanging out in the machine.
When the cover is fully on, I’ve never found these bugs…please help, thank you

This is a Springtail and it is a common insect found worldwide.  They are often found in homes if conditions are right.  They are benign and will not harm you or your child.  We are quite certain the steam kills them when the bottles are being sanitized.  Outdoors they aid decomposition and according to BugGuide:  “They may also graze on spores of molds and mildews, especially indoors where there is a lack of other food sources.”  They could be considered beneficial inside the home as they would inhibit the growth of mold and mildew.

Thank you so much Daniel, it relieves me to know that they are benign.  Have a good one!

Stinging Slug Caterpillar

Dear Asyraf,
This is a Stinging Slug Caterpillar in the family Limacodidae, but it appears different from this Malaysian Stinging Slug Caterpillar from our archives or this Blue Striped Nettle Grub, also from Malaysia.  While we can provide a family name, we are unable to provide you with a species at this time.

Broad Headed Bug

Dear Ken,
This is a Broad Headed Bug in the genus
Hyalymenus, possibly Hyalymenus longispinus which is pictured on BugGuide and which is endemic to Florida according to BugGuide.  Though there are no photos available of the other two species, BugGuide notes:  “3 spp. restricted to FL (H. longispinus, H. notatus, H. potens).”

Subject: Grasshopper? In Los Angeles?

Hi Bugman,
Growing up in Wisconsin, grasshoppers were a common sight, but I haven’t seen them here in LA. I wonder if it’s a consequence of global warming and the humidity we experienced last summer.
Should we be concerned for our gardens?
Thx, Jeff

Bush Katydid

Dear Jeff,
We do have native Grasshoppers in the Los Angeles area, and some like the Gray Bird Grasshopper are quite large, however the insect in your photos is a Bush Katydid in the genus
Scudderia.  Katydids and Grasshoppers are in the same insect order, and they look very similar.  The easiest way to distinguish them from one another is the antennae.  Katydids are longhorned Orthopterans will long antennae and Grasshoppers have much shorter antennae.  We believe this is a Fork Tailed Bush Katydid, Scudderia furcata.  Most Bush Katydids are green, but there is a photo of a brown individual on BugGuide.  See BugGuide for additional information on the Bush Katydids.  Like Grasshoppers, Katydids feed on plants, but unlike Grasshoppers, Katydids do not form great masses of individuals that eat everything in their path like the infamous plagues of locusts.  We allow Katydids to live in our Mount Washington, Los Angeles garden.  They love feeding on the petals of roses, but they don’t really damage the plants much.  Your individual is a female as evidenced by the sickle shaped ovipositor at the tip of the abdomen.

Hello Bugman!
My son found this large hawkmoth caterpillar on our synthetic lawn. It’s about the size of an adult’s index finger and I guessed it was looking for a place to burrow for pupation. We put it in a jar full of soil and it dug right in, so we’re sure of the family identification.
We’d love to know what species to expect in the jar in a few weeks! I searched the web but found nothing similar.
Thanks for your excellent site!

Death’s Head Hawkmoth Caterpillar

Hi Ben,
We wish your photo had better detail.  We will try to determine the species identity of this Hornworm.
  We quickly located this matching photo on the Natural History Museum website where it is identified as the Death’s Head Hawkmoth Caterpillar, Acherontia atropos.  There are also matching photos on Shutterstock and Wikimedia Commons.  This is not the typical coloration of the Death’s Head Hawkmoth caterpillar which is more common in its yellow form.

Every summer we have a plague of lax beetles and it is driving me to the point of wanting to move house. We have all suffered the painful blisters and just now we had to remove a large lax beetle from out 11 month baby’s face. Ran inside and washed it with running water but still waiting to see what emerges. I know you do not endorse eradication but summers are rather unpleasant living in fear of these little bugs and I would really like some tips on how to control them and protect my family. We live in the country and work, play and eat outside whenever the weather is fine and we enjoy our diverse selection of wildlife and insects. These beetles are something else and I am scared to let my young children play out on the lawn. Each morning I am sweeping up tens of these from the floors and decks around the house.

Lax Beetle

Dear Pania,
We have to confess that we had no idea what Lax Beetles were until we began to research you submission.  We learned on Nature Watch that Lax Beetles are False Blister Beetles in the family Oedemeridae.  We also learned on Nature Watch that “Adults contain the toxic cantharidin in their corporal fluids as a defensive mechanism; several species show brilliant and metallic blue, green, gold or coppery, often combined with yellow, orange or red, aposematic colourations. In temperate regions, adults are mainly polyphagous pollen and nectar-feeding, and diurnal in activity. In tropical areas, most are nocturnal and are attracted to light.”  We then learned the identity of your beetle, the Striped Lax Beetle,
Thelyphassa lineata, on Project Noah.  Photos can also be found on the Australian government page PaDIL.  The New Zealand Landcare Research website indicates:  “Attracted to lights  Grubs found in rotten wood  Adults probably feed on pollen and nectar.”  We do not give extermination advice, but you might be able to control the numbers of Lax Beetles by controlling their needs.  Do not keep outdoor lights on at night and try to secure window screens so they cannot get indoors at night.  Remove all rotting wood from the vicinity and try to determine which pollen producing plants the adults are attracted to and remove those plants from your yard.

Thank you for your quick response and the useful links.
We have done a bit of research in the past and have come up with more-or-less what you have said. We do also have the spotted lax beetle here and I am pretty sure we have the odd “Dark-patch lax beetle” as well. Haha – There is nothing “false” about the blisters they produce. The biggest problem is that we are surrounded by pine trees and that is, presumably, where they breed. We can not identify any nectar producing plants that would attract them to the garden, except lemonwood trees but they are not flowering at present. The lights of the house at night attract them for sure, so we keep windows and doors closed after dusk. They may be attracted to the lucerne flowering in the paddock.
I don’t think any of the more colourful varieties of blister beetle are present in New Zealand.
They are definitely nocturnal here (although we are in a temperate, not tropical location). They fly at night, starting in the early evening, (not sure about feeding patterns), during the day they hide in shady, damp areas, and are often in the folds of the sun umbrella at the outdoors table or in the crevices of wooden structures. They do not usually fly during the day and are usually found on their backs with legs moving when I sweep them up off the floor and deck in the morning. If turned right way up, they walk quickly along floors and walls and people. If knocked off of high object, they usually just fall down to the ground and start walking rather than fly off.
If a lax beetle lands on you the most important things to do are: Do not squash it – Do not rub it or brush it off slowly, use a very quick flick to get it off, hopefully before it can release the toxin from its joints. Then wash the area of skin under plenty of running water. That seems to work in most cases for us and my baby’s cheek seems to be OK after following the above procedure. Where we have problems is when we do not notice the beetle on the body and then maybe accidentally squash it a bit. We have often been blistered while sleeping. Apparently they are quite toxic if accidentally ingested. That is unlikely due to their large size, but a baby might pop one in his mouth out of curiosity. They can be eaten by stock, e.g. in hay but we have not noticed any problems with our stock.
On the positive side, while the blisters can develop into fairly large, painful erosive lesions that take several weeks to heal, there does not appear to be long-term scarring. The blisters themselves are not painful, it is the erosion left after the blister pops and skin lifts that is painful. I had a large blister across my chin three years ago. It took about 2 months to heal but there is no residual scarring now and my older son had a blister approx 7cm diameter on the top of his head when he was a 3 month old baby that healed up fine.
It would be useful to know:
What is the flight distance of an adult?
What do the nymphs or larvae look like? (I haven’t found any pictures on the internet)
What is the exact life-cycle.
Are there any specific plants that they feed on?
How quickly does the cantharidin toxin break down and can it be released from dead beetles?
The published literature seems to be limited.
Thanks again

Hi Pania,
This will take considerable research.  For the moment, we will feature your question and we hope one of our readers might be able to assist in this matter.
