Girls Bug a Preying Mantis

Dear gigi,
Even though they might be bothering this Preying Mantis, it isn’t nice to call girls “bugs”.

Dear Daniel,
I love bugs and love this site so much. I find myself lost in the archives of such fascinating images and information often. I write for a collaborative blog called A COLLECTION OF ( I am going to be posting about an orb weaver (attached) and wondered if might be interested in doing an interview with us. (if you are I can send you the questions) We would be so thrilled to have you on the blog! Either way – if you can help in identifying this spider that would be great! I hope to be posting soon in conjunction with the spider pavilion exhibition.

Western Spotted Orbweaver

Hi Stefani,
We sometimes have difficulty identifying the many different species of Orbweavers, but we believe this is the Western Spotted Orbweaver,
Neoscona oaxacensis, which Charles Hogue, in Insects of the Los Angeles Basin, wrote is “our most common orbweaver; in late summer and fall, its moderate=sized webs adorn gardens everywhere in the basin.”  Thanks for your compliment.  Send your questions our way and we will try our best to answer them.

Hanging Thief Robberfly with Prey

I’ve been trying to get a photo of this bug for about three weeks…It is normally very evasive and won’t land anywhere near my camera.
Today it landed in front of me and let me get a photo of it.
A few minutes later it caught a bee and hung from a small redbud tree ,not only letting me take photos but also touching it get a better pic.
From looking at a Bug site it appears to be a Hanging Thief Robberfly.

Hanging Thief and Prey

Hi Chris,
Thanks so much for sending us your wonderful photos of a Hanging Thief with its prey.  Though it is a member of the genus
Diogmites, we are uncertain of the species.

Water Striders

Hi David,
Water Striders are such common insects on ponds, lakes, streams and slow moving rivers, that we cannot understand why they are so underrepresented on our site.  Because the spread of their legs distributes their weight evenly across a greater surface area, Water Striders are able to skate across the water without breaking the surface.  Water Striders feed on small insects that fall onto the water’s surface.  One group of ocean dwelling Water Striders contains the only true pelagic insects that are found far out to sea on the open ocean.
