צרעכבישית חומה בשמורת הבניאס

צרעכבישית חומה
צילומים: עופר שנער, רשות הטבע והגנים.

היום (שבת) נצפתה צרעכבישית חומה בשמורת הבניאס. צרעכבישית היא צרעה שצבעה חום כהה, כנפיה צהובות ושוליהן כהים. צרעה זו צדה עכבישים כמזון לזחליה. משאיתרה הנקבה עכביש היא עטה עליו ועוקצת אותו בחזה. אז היא נושאת את העכביש המשותק למחילה שחפרה, מטילה עליו ביצה אחת, וסותמת את הפתח. הזחל הבוקע טורף את העכביש המשותק ומתגלם. הצרעות הבוגרות ניזונות מצוף.
