This was taken in my garden on the island of Crete. Can you tell me if it is poisonous? Fascinating to find many different spiders here. Last one we found was a wolf spider.

Male Ladybird Spider

Male Ladybird Spider

Dear LindaJ,
Your endangered male Ladybird Spider in the genus
Eresus, most likely Eresus sandaliatus based on information included on the Spiders of NorthWest Europe site which has images from Crete indicating that the species can be identified by the black and white hind legs.  Most spiders have venom, but very few species of spiders are considered dangerous to humans.  To the best of our knowledge, the Ladybird Spiders are considered harmless, and the fact that they are endangered through much of their range indicates that no methods should be used to threaten them if they are found in your garden.

Oil Beetle

Oil Beetle

Dear Barry,
At first we thought this was going to be a routine identification of an Oil Beetle in the genus
Meloe, and the only item of significance is that all of our many reports are from North America and we did not realize that the genus was represented in Europe.  As we commenced research, we were led to BugLife where we learned:  “Oil beetles are incredible insects, but they are also under threat. Three of UK’s native oil beetles are now extinct, and the remaining five species have suffered drastic declines in their distributions due to changes in the way our countryside is managed. …  Oil beetles have been identified as priorities for conservation action through the UK Biodiversity Action Plan (UKBAP) – meaning work needs to be done to conserve them and their habitats. To help landowners and managers our oil beetle management sheet is now available. ”   Another page on BugLife provides this information:  “Oil beetles are conspicuous, charismatic insects which are often encountered when out walking and enjoying the countryside. Their habit of seeking out bare compacted earth in which to dig nest burrows means that they are frequently seen on footpaths. The best time of year to look for oil beetles is March to June.
Please keep a look out for these beetles when walking in meadows, grasslands and open woodlands and let us know if you find them by submitting your sighting records and uploading your photos. Your records can make a real difference to our oil beetle conservation work.”
  We would urge you to be a citizen scientist and submit your sighting.  Since neither BugLife page included images of Oil Beetles, we are also linking to this BBC Earth News page where it states:  “Conservationists are asking the public to take part in the first survey of the UK’s threatened oil beetles.  These large, lustrous insects thrive in wildflower-rich grasslands and heaths – areas of habitat that are being lost.  In the last hundred years, half of the country’s eight native species of oil beetle have disappeared.”  We are featuring your submission.

Just sharing. Our big tree is a hatching ground for brood XXIII this year (At least due to our location I think they are 13 year and not 17 year periodicals). I’ve been out every night and have seen a handful each time. Last night looked like a scene from a horror flick if you looked over your head there were more cicadas than leaves. It was raining bugs under that tree. Bats were dive bombing past us and scooping them off the trunk. The ground and trunk were literally crawling as 100’s if not 1000’s of them were headed to molt. We caught some video last night. I snapped some pics this am and figured I would share some of the various stages of them molting.
Love your page!

Thirteen Year Cicada

Thirteen Year Cicada

Dear Jess,
We are positively thrilled by your submission, and we will be featuring your images to document this Brood XXIII emergence of 13 Year Cicadas.  As you have indicated, Periodical Cicadas are divided into two main groups, those that remain underground for 17 years and those that remain underground for 13 years, and the latter are found in more southern states.  Additionally, populations are further divided into broods based on the years they emerge and the locations of those broods.  To further complicate matters, some individuals emerge earlier or later, and if those individuals encounter favorable conditions, new broods may eventually result.  According to, Brood XXIII is known as “The Lower Mississippi Valley Brood.”  According to the Brood page on Magicicada.Org, your Brood XXIII individuals are right on schedule.  According to Cicada Mania:  “As of May 10th, it would appear that the emergence has begun in Louisiana and Tennessee as well.  The 2015 Brood XXIII emergence has begun! ”  Cicada Mania also notes:  “The cicada species that will emerge are
Magicicada tredecim (Walsh and Riley, 1868); Magicicada neotredecim Marshall and Cooley, 2000; Magicicada tredecassini Alexander and Moore, 1962; and Magicicada tredecula Alexander and Moore, 1962. These periodical cicadas have a 13-year life cycle. The last time they emerged was 2002. According to John Cooley of, Giant City State Park, Illinois is a good place to observe both M. tredecim and M. neotredecim.”

Pink Glowworm

Female Pink Glowworm

Dear DiAnn,
We believe your female Pink Glowworm (actually a Firefly) is
Microphotus angustus, which is pictured on BugGuide, though there is a dearth of information on the site.  Luckily our favorite text for local species in our area, The Insects of the Los Angeles Basin by Charles L. Hogue, provides a wealth of information:  “the female of the Pink glowworm (which is 1/2 in.,or 13 mm, long) communicates her location to the male (1/4 in., or 6 mm, long) by emitting a continuous uniform luminescent glow.  The adult male has the usual firefly beetle form, but the female is ‘larviform’ (wingless and elongate like the larva …).  The males are not seen as often as the females because they give light only when disturbed, and the light is weak and not used in communication.  The female is fairly common in late spring to early summer in the foothill canyons  … .  Found at night by its glow and in the daytime under stones lying on the leaf mold in grassy areas, the adult Pink Glowworm is easily recognized by the pink color of the flattened segments;  the terminal segments are yellowish.  The segments of the larvae of both male and female are blackish with pink margins.”  We are very excited to include and to feature your Pink Glowworm documentation.

Subject: Fly?…
Location: Houston
April 30, 2015 10:58 am
Hello bugman,
I noticed a large cluster of flying bugs of some sort on my tree today. 2 groups. From a distance they appear black, like large gnats? Up close they’ve got 6 legs it appears, long antennae, and wings. The wings are a very detailed combination of black and gray colors, outlined in white with a white solitary spot. Very beautiful looking up close. Just not sure if these are invasive /destructive to my tree/garden and wanted to check what they were. The closest thing I’ve been able to find is a picture winged fly but there are so many I wasn’t sure. I have a video as well if you’d like it. You’re help is truly appreciated!

Dear Alma,
These benign Barklice,
Cerastipsocus venosus, might appear alarming when they are seen clustering on a prized tree in the yard, but gardeners have no cause for alarm.  Barklice feed on lichens, and they will not harm your tree.  Barklice are sometimes called Tree Cattle.  Your image is of winged adults.  Wingless Barklice nymphs are boldly striped.  We just realized it is the first of May and we need to select a new Bug of the Month, so we have selected your excellent image of Tree Cattle as the featured posting of the month.

You guys are AWESOME! I can’t thank you enough for your help and information!!!  I’m a huge science fan so I love exploring and trying to figure out what things are. I also know how busy you guys must get, so I will definitely be helping with a donation. I also let people know about your site when they are trying to figure out bugs. If you ever need help for rebranding/redesigning let me know (I’m a professional graphic designer). I’m happy to help if you need it!
You have a great weekend!
Alma Soto

Thanks for the offer Alma.  We got our start many years ago on the now defunct American Homebody site, and we still prefer our homey look to the more high tech sites.

I can most certainly understand and respect that!
For what you guys do… It actually works.
Again thank you guys so much for your help, and prompt response. i’ve made sure to tell all my friends about you guys, and have already tweeted you out. :) you guys have helped me before I remembered for a bug I experienced when we lived on job assignment on Venezuelan Penninsula that they call pachaco – it was I found out thanks do you guys a Solifugae (all I could remember was that their body looked like a cross between an ant, spider and an earwigi- they were fierce looking, fast, and scared the living daylights out of me). so again, thank you guys for all you do!
