Stenopodius texanus Schaeffer

On 10 November 2012, I found adults of this species feeding on foliage of an Abutilon Mill. (Malvaceae) , probably either A. incanum (Link) Sweet or A. parvulum A. Gray , near Tucson, Arizona. They ate small, round to oval patches in the upper surface of the leaves. Among the leaves of this plant, I found a single blotch mine, which was largely clean with the frass all deposited in a mass at one end ( Fig. 12 ). The oval egg was found adjacent to the frass deposit, inserted in a pit chewed in the upper epidermis. The completed mine was about 1.5 cm 2. The adult S. texanus emerged by 18 November, chewing an exit hole through the upper epidermis (specimen in USNM). This is the first rearing record for this beetle, which has previously been collected only as adults from several species of Sphaeralcea A. St. -Hil. ( Malvaceae ) ( Staines 2006).

Figs. 7–12. 7) Presumed mine of Microrhopala rubrolineata in Brickellia betonicifolia leaf; 8) Brickellia betonicifolia leaf with skeletonizing by adult Octotoma marginicollis. The mine along the leaf margin was possibly made by a larva of this species; 9) Hog-peanut (Amphicarpaea bracteata) leaf with mine of Odontota mundula overlapping mine of Leucanthiza amphicarpeaefoliella. The latter is visible as an indistinct band of frass in the lower left; 10) Mine of Odontota scapularis in groundnut leaf, with excrement-covered egg mass at right edge of photo; 11) Odontota scapularis egg mass containing pupae of parasitoid wasps; 12) Mine of Stenopodius texanus in Abutilon leaf.
