I was trying to identify this moth and came across your site. It seems I have found a silk moth. The unusual thing is I live in Michigan. I took this photo in my back yard May 26, 2012. I’ve never seen one of these before.

Hi – We found this spider in our backyard in Southeastern PA. It was hiding in our rock pile. It was @ 1.5-2” long. It’s mostly white, hairy with back spots. Do you know what it is and if it’s dangerous? Thank you!

Canopy Jumping Spider

Dear MPL,
We are very happy to post your image of a Canopy Jumping Spider,
Phidippus otiosus, which we quickly matched to a photo posted to BugGuide.  The size is listed as “Body length 8-12 mm (male), 12-18 mm (female)”  on BugGuide, so we think your size estimate is a bit of an exaggeration.  BugGuide lists the habitat as “Canopy of deciduous and mixed deciduous/pine forests.” so we are curious if you live near a wooded area.  Jumping Spiders do not pose a threat to humans, though we cannot discount that a large individual might bite if carelessly handled, but the bite will do little more than to cause local discomfort.

Hi Mr Bugman,
I was lying in bed when I heard this clicking on the wall next to it, turned out to be this little guy, I say little he is pretty big, with a pointed bottom and a really hard shell! never seen this sort of beetle in England before, I’m guessing its down to the really hot weather we’ve been having in the last few days.

Subject: Caterpillar/Worm is Devastating Violas

I have never seen this bug before, nor can I find it online. They are DEVASTATING my Violas! This is the first and ONLY year that anything has attacked the Violas. They range in size from approx. 2mm to 1 or 1.5 inch. They do not ”loop” when moving.The larger ones seem to prefer the flowers. The smaller ones have been found under the flower or on a leaf. They are also on a windowbox of Pansies but not the hanging basket. Very little damage to the Pansies but ALL the Violas have been devastated! They are on Every single Viola plant I have. Which are spread out amongst 6 different areas. They are ONLY on the Violas even the ones that are under or touching other plants. Which include Dianthus, Roses, and a small evergreen tree. Well, one miniature rose does have some holes on some of the leaves and some of the buds were black edged, but, they were this way last year also. They are very soft-bodied, however, dormant oil did not seem to have any effect. I have re sorted to hand picking and squishing or throwing in soapy water. Also, when squished, the ”guts” are dark green.
The 3rd picture is of the white Viola prior to being infested. They are out of control! Please help!

Variegated Fritillary Caterpillars

Hi Melissa,
We hope we responded before there was any large scale extermination for this matter.  These are the caterpillars of the Variegated Fritillary.  The chrysalis of the Variegated Fritillary is a beautiful gold-flecked object.  The adult Variegated Fritillary butterflies are lovely creatures.  Many gardeners put in plants to attract butterflies, and while nectar producers are vital, providing food plants for the caterpillars is another decisive factor needed to ensure healthy butterfly populations.  The plants will grow back new leaves and flowers and you can enjoy the adult butterflies in a few more weeks.

Could you please identify this large spider that is working the night shift outside our house in Southwest Michigan? It is May and 70-80degrees during the day. The second picture measures the lines on the concrete at 4 inches apart. I have never seen anything this size in 50 years here. Thank you.

Hi guys,
Hope you like these shots of Crypsiphona ocultaria. A very drab looking moth in the Geometridae until you see underneath.
Winter is closing in and this guy was very reluctant to move which allowed me to get it into a container to shoot the lovely colours underneath.

Geometrid Moth: Crypsiphona ocultaria

Hi Trevor,
Earlier in the year we received two images, upper and lower wing views, of
Crypsiphona ocultaria, and we identified it as the Red Lined Looper Moth on the Brisbane Insect website.  The markings on the lower wings are quite pretty and distinctive, and we can’t help but to wonder if there is any evolutionary significance to it.
